Hello everyone

I would like to use dynamic_cast in C++ Matlab-Mex files. This seems
to be okay if I use g++ 2.96 but crashes with a segmentation fault
when I use g++ 3.02.

I will have to use g++ 3.02 because of new features in the standard
library.

Does anyone have similar experiences or know any advice what to do?

Cheers
Dirk

Think hard about the following question:

"Have I done anything to provide potential helpers with all necessary
information?"

Things like source code usually help ;-)

Make sure that you use g++ to compile and link your MEX-file.  Output
from mex -v might help as would a stack trace from the debugger when you
seg fault.  A snippet of code would also help.
