std::basic_string<wchar_t>: segmentation fault while accessing any member functions

[mufasa]

have a type given by:

typedef std::basic_string<wchar_t> mystringtype;

at one instacne of my program, i have a vairable called 'abc' of type
mystringtype. When i try to access the .c_str() or even .length()
functions, I get a segmentation fault. Is there a way to check what
exists in 'abc' because it's definitely holding something .. though
looks like some corrupt memory address ..

Probably, you overwrited the memory used by the string.

Yes, use a debugger or dump the string's binary representation. Having
checked up the string implementation you can then map the binary dump with
string's members.
