I have this output when trying to debug

Program received signal SIGSEGV, Segmentation fault

0x43989029 in std::string::compare (this=0x88fd430, __str=@0xbfff9060) at /home/devsw/tmp/objdir/i686-pc-linux-gnu/libstdc++-v3/include/bits/char_traits.h:253

253 { return memcmp(__s1, __s2, __n); } Current language: auto; currently c++

Using valgrind I getting this output

==12485== Process terminating with default action of signal 11 (SIGSEGV)

==12485== Bad permissions for mapped region at address 0x0

==12485== at 0x1: (within path_to_my_executable_file/executable_file)
