>Description:
This was first noticed with g++ but potentially affect C as well.  It only affects ports that don't use an epilogue for function returns.

Incorrect code will be generated for the following test program when compiled with g++:

char *
srealloc (char *p, char *q, int i)
{
  if (i == 0)
    return p;
  else
    return q;
}
>How-To-Repeat:

>Fix:
A patch to fix the above problem is presently being tested.
If testing is successful, I will submit it later today for
review.
