Re: [Dev-C++] Segmentation Fault - Debugging

[Jamiil A. <jal...@gm...>]

Per and Adam, thank you very much for the hand.
Using Per's suggetion I used the DOS prompt to run gdb and tb, and as 
requested by Adam, here is the slice of code that is causing all the 
problems.
hpp file
#include <glibmm/ustring.h>
....
Glib::ustring* str;
...
cpp file
if (str->empty()){str = new Glib::ustring("Unknown");}
...

'gdb' reports that the error is in basic_string.h, line 261. I am compiling 
using mingw32 v 3.4.4
In a WinXP machine.
What has me comfused is that I am not using the std library, but the Glib 
library; yet the error comes from the std library
Can anyone help?
