Abort (uncaught bad_weak_ptr()?) from Connection::onClientDisconnected().

[toojays]

rtags cb817751 dumped core. I'm not exactly sure what I was doing at the time, but the backtrace looks like:

Core was generated by `rdm --rp-nice-value=10'.
Program terminated with signal SIGABRT, Aborted.

Hi

Can you check your rct-config.h and see if

define HAVE_EPOLL

is defined or not?

Anders

[toojays]

It is defined:

#ifndef RCT_CONFIG_H
#define RCT_CONFIG_H

#define HAVE_BACKTRACE
#define HAVE_CLOCK_MONOTONIC_RAW
#define HAVE_CLOCK_MONOTONIC

I believe this https://github.com/Andersbakken/rct/pull/30 fixes it. Can you verify?

[toojays]

This looks fixed now. Thanks Anders.

[Andersbakken]

My pleasure. It was even a contribution. OSS at its finest :-) https://github.com/Andersbakken/rct/commit/0be84220cadeaf15c2111582d16dfc3c1859e8ce
