A problem internal to GDB has been detected, further debugging may prove unreliable. ----- Backtrace ----- --------------------- /cygdrive/d/a/scallywag/gdb/gdb-12.1-1.x86_64/src/gdb-12.1/gdb/infrun.c:2553: internal-error: resume_1: Assertion `pc_in_thread_step_range (pc, tp)' failed. So, now to the description of circumstances that cause it: Program is: https://github.com/eshavlyugin/Preferans I compiled it after some trivial fixes ( like referencing explicitly boost:array; boost:unordered_map, even so it should not be needed, i.e. gcc should be well able to figure out what is being used, change of the condition if (window == null) to if (!(window)) and setting C++ language version C++11 because of additional requirements put on comparators -- them having to use some const in explicit -- so by and large because gcc is too feisty at all the wrong places ;-) ). Now every time I select Game->New in the GUI it crashes and crash seems to be related to LocalPrefServer.cpp:395 line, so I set breakpoint there and attempted to single-step through what appears to be platform's (Cygwin+system libraries) bowels. Now what?
