Problem with CStdString

[Yogesh]

hi,
  I am looking into a code written by someone else. This guy has used 
the string class CStdString.(found at 
http://home.earthlink.net/~jmoleary/stdstring.htm).
The code is supposed to be working on codewarroir 9 on mac os 10.3.
When I tried to move the code on gcc 3.3 the following assignment 
crashes.

CStdString bString = L"Hello World";
CStdStringA aString = bString;   ->//gcc Crashes here

Can anybody, who has worked with above class, suggest a solution...

Thanks
Yogesh
