Same problem. :( Similar backtrace if I interrupt it while it's in its 100% CPU loop. Seems to be during shared library initialization: (gdb) run Starting program: /usr/games/gnubg [Thread debugging using libthread_db enabled] Using host libthread_db library "/lib/x86_64-linux-gnu/libthread_db.so.1". ^C Program received signal SIGINT, Interrupt. memcpy (__dest=0x5555559b1070, __src=0x7fffea08541e, __len=6) at /usr/include/x86_64-linux-gnu/bits/string3.h:53 53 return __builtin___memcpy_chk (__dest, __src, __len, __bos0 (__dest)); (gdb) bt #0 memcpy (__dest=0x5555559b1070, __src=0x7fffea08541e, __len=6) at /usr/include/x86_64-linux-gnu/bits/string3.h:53 #1 0x00007fffe836aea2 in ??
