Exceptions do not work for me. Here the sample file I used:

#include <exception>

class My_Exception : public exception
{
public:
  My_Exception()
  {
  }
};

int main()
{
  try
  {
    throw My_Exception();
  }
  catch (My_Exception & error)
  {
  }
  return 0;
}

and here the result from running it:

O:\SPORT>ttt.exe

O:\SPORT>symify ttt.exe

and after this, I thought, I simply try my good old gcc 2.81 to verify
that it works as I expect (and it worked with 2.81) and I got the
following: (this might be a problem with gcc 2.81
and the libc it was linked with, but I mention it here for completeness)

OK, so I thought to use my good old gcc 2.81 driver to execute the 2.951 version
and got: (this seems to be now a real gcc 2.951 problem on DJGPP)
