Formatting any Verilog file gives "Assertion '__pos <= size()' failed" #8

Closed IsaacJT closed 4 years ago

Hello, I am using Fedora 29 and running the utility on any Verilog file gives the following output:

iStyle 1.21 (Fast and Free Automatic Formatter for Verilog Source Code)
               (Created by haimag, Report Bugs: haimag@gmail.com)
               (Thanks to Tal Davidson & Astyle)

The .orig file is created, but the file to be formatted is truncated down to only a couple of lines.

The output file is probably truncated because the failing assert shuts down program while it is still formatting it.

Your printout says (core dumped); are you still able to reproduce the bug and get a core file? If you can get into GDB (GNU debugger) to get a backtrace it would be really helpful. (The command to do that in the GDB console is simply backtrace and it prints it to your terminal.)
