I will did this if I have more time.

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

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().
