Crash when using raw KISS TNC

I have custom protocol that I'm working on(https://github.com/vvanders/nbplink) that I was hoping to use Direwolf as a raw KISS TNC for Signal Link and other soundcard based radio interfaces.

With the current version(1.3) Direwolf is crashing for me with the first packet sent across. I have packets successfully working on a Kenwood D710 and Mobilinkd via serial ports so I'm somewhat sure that the KISS framing is valid.

I'd be happy to dig into Direwolf more but I can't seem to build it for my platform(Win10) a "make direwolf" from cygwin w/ MinGW tools on the path returns:

$ make direwolf
gcc -Wall -Ofast -msse -Iregex -Iutm -Igeotranz -mthreads -DUSE_REGEX_STATIC -g   -c -o beacon.o beacon.c
beacon.c:68:12: error: conflicting types for 'localtime_r'
 struct tm *localtime_r(time_t *clock, struct tm *res)
            ^
In file included from beacon.c:40:0:
C:/msys64/mingw64/x86_64-w64-mingw32/include/time.h:269:34: note: previous definition of 'localtime_r' was here
 __forceinline struct tm *__cdecl localtime_r(const time_t *_Time, struct tm *_Tm) {
                                  ^

Anyway, repro is pretty simple, Win10, v1.3 I'm sending the following bytes over the TCP port:

Wrote [192, 0, 20, 163, 178, 115, 107, 92, 77, 140, 0, 0, 0, 0, 107, 92, 77, 140, 0, 0, 0, 0, 32, 116, 101, 115, 116, 10, 140, 153, 192]

#
#   (3) DIGIPEATER  -  configure digipeating rules.

#
# In the simplest form, just specify the speed. 
# 

MODEM 1200
#MODEM 300
#MODEM 9600

#
# These are the defaults should be fine for most cases.  In special situations, 
# you might want to specify different AFSK tones or the baseband mode which does

#
# On HF SSB, you might want to use multiple demodulators on slightly different
# frequencies to compensate for stations off frequency.  Here we have 7 different
# demodulators at 30 Hz intervals.  This takes a lot of CPU power so you will 
# probably need to reduce the audio sampling rate with the /n option.

# If not using a VOX circuit, the transmitter Push to Talk (PTT) 
# control is usually wired to a serial port with a suitable interface circuit.  
# DON'T connect it directly!
#
# For the PTT command, specify the device and either RTS or DTR.
# RTS or DTR may be preceded by "-" to invert the signal.
# Both can be used for interfaces that want them driven with opposite polarity.

# The Data Carrier Detect (DCD) signal can be sent to the same places

# Dire Wolf acts as a virtual TNC and can communicate with
# client applications by different protocols:
#
#   - the "AGW TCPIP Socket Interface" - default port 8000
#   - KISS protocol over TCP socket - default port 8001
#   - KISS TNC via serial port
#

#AGWPORT 8000
KISSPORT 8001

#
# Some applications are designed to operate with only a physical
# TNC attached to a serial port.  For these, we provide a virtual serial
# port that appears to be connected to a TNC.
#
# Take a look at the User Guide for instructions to set up
# two virtual serial ports named COM3 and COM4 connected by
# a null modem.
#
# Using the  configuration described, Dire Wolf will connect to 
# COM3 and the client application will use COM4.

# First you need to specify the name of a Tier 2 server.  
# The current preferred way is to use one of these regional rotate addresses:

#   noam.aprs2.net      - for North America
#   soam.aprs2.net      - for South America
#   euro.aprs2.net      - for Europe and Africa
#   asia.aprs2.net      - for Asia
#   aunz.aprs2.net      - for Oceania 

#IGSERVER noam.aprs2.net

# You also need to specify your login name and passcode. 
# Contact the author if you can't figure out how to generate the passcode.

#IGLOGIN WB2OSZ-5 123456

# That's all you need for a receive only IGate which relays
# messages from the local radio channel to the global servers.

# Some might want to send an IGate client position directly to a server
# without sending it over the air and relying on someone else to 
# forward it to an IGate server.  This is done by using sendto=IG rather
# than a radio channel number. Overlay R for receive only, T for two way.

#PBEACON sendto=IG delay=0:30 every=60:00 symbol="igate" overlay=R lat=42^37.14N long=071^20.83W 
#PBEACON sendto=IG delay=0:30 every=60:00 symbol="igate" overlay=T lat=42^37.14N long=071^20.83W 

# To relay messages from the Internet to radio, you need to add
# one more option with the transmit channel number and a VIA path.

#IGTXVIA 0 WIDE1-1

# You might want to apply a filter for what packets will be obtained from the server.
# Read about filters here:  http://www.aprs-is.net/javaprsfilter.aspx
# Example, positions and objects within 50 km of my location:

#IGFILTER m/50 

# That is known as a server-side filter.  It is processed by the IGate server.
# You can also apply local filtering to limit what will be transmitted on the 
# RF side.  For example, transmit only "messages" on channel 0 and weather 
# reports on channel 1. 

#FILTER IG 0 t/m
#FILTER IG 1 t/wn

# Finally, we don't want to flood the radio channel.  
# The IGate function will limit the number of packets transmitted 
# during 1 minute and 5 minute intervals.   If a limit would 
# be exceeded, the packet is dropped and message is displayed in red.
