------- Additional Comments From reichelt at gcc dot gnu dot org  2003-10-16 23:29 -------
Here's a reduced testcase that crashes cc1plus as well as cc1:

=================================
char* foo(char**);

void bar()
{
    char ar[1], *p, *q;

    p = foo (&q);
    if (p == ar) *p = 0;
}
=================================

According to Phil's regression tester the bug was introduced
between 2003-10-12-ssa (#106) and 2003-10-13-ssa (#107).

Because the bug has nothing to do with cygwin, I removed target
and build triples.
