   Hi Yuanhui,
thanks for trying to debug this...

   First, concerning the optimized out problems,
it would be easier if you would recompile
GDB without optimization:

make clean all CFLAGS="-gdwarf-2 -O0"

After that, you should get optimized out variables...

I will did this if I have more time.




I also installed CodeBlocks to test if I can reproduce your crash, but I never got any ...

The codeblocks.exe was built myself, which has debug information in it.



Could it be that some weird DLL's have unnamed sections? Could you try to insert if (sections[i] && section[i].name) before
      if (strcmp (sections[i].section_name, section_name) == 0)
        return i;
to confirm that the problem originates here?


I add a line: static int get_pe_section_index (const char *section_name, struct read_pe_section_data *sections, int nb_sections) { int i; for (i = 0; i < nb_sections; i++) if (section_name && (&sections[i]) && sections[i].section_name) if (strcmp (sections[i].section_name, section_name) == 0) return i; return PE_SECTION_INDEX_INVALID; }


But still the same crash in strcmp().
