--- Comment #4 from Bill Schmidt <wschmidt at gcc dot gnu.org> ---
Hm. I compiled it as stated and I see a bunch of code that appears to be
storing the ".disk/" string. So it doesn't look like dead code elimination.
Perhaps a branch is short circuiting this, or the address of where to store it
has been corrupted.
I don't have any way to confirm that I'm reproducing the problem when I
compile, from what's given here. It might be helpful to provide the full test
case without ellipses, and the failure message given by the test.
