------- 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.
