Compile the attached project (really difficult to trim it down) using two different options. First, using -glh, then using -g. The first one raises nothing (program runs fine), while the second raises segmentation fault. When debugged deeper using gdb, the second gives this backtrace:
Program received signal SIGSEGV, Segmentation fault. 0x004091da in SYSTEM_REMOVE_FREED_FIXED_CHUNKS$POSCHUNK () (gdb) bt #0 0x004091da in SYSTEM_REMOVE_FREED_FIXED_CHUNKS$POSCHUNK () 0000001 0x00000010 in ??

() 0000005 0x0040c0e1 in SYSTEM_EXE_ENTRY$TENTRYINFORMATION () Jonas told me to discuss it here due to unclearness whether this is a bug in my program or in fgl or wherever else.
