Here is something that I use to get kind of what you describe.  I
plucked the code from something someone else posted, I dont remember
exactly who.  Whoever did send me a mail and I'll put thier name in the
sources..

Here is the code:

//----------------------------------------------------------------------------
// abort program with stacktrace suitable for symify
// if -g was used for compiling

void _detl_assert (const char* test, const char* file, const int line)
   {
   long *bp=(long*)&bp+1;

   FILE *stream = fopen("assert.log","w");

   fprintf(stream,"DETL assertion %s at line %i in %s
failed!\n",test,line,file);

   while(*bp)
      {
      fprintf(stream,"  0x%08lx\n",((long*)bp)[1]);
      bp=(long*)*bp;
      }
   fclose(stream);

   exit(255);
   }

The output gets written to an assert.log file and if you symify that
file you should get the stack trace.

Good luck.
