[Bug other/40623] New: variable seems to be optimised out incorrectly

[galtgendo at o2 dot pl]

I'm in doubt about exact compiler info,
cause I want to report a bug from Gentoo bugzilla,
where reporter was using 4.3.2, but I could reproduce it
with 4.4.0.
We're both on x86.
It's http://bugs.gentoo.org/show_bug.cgi?id=276146.

A rather simple code fragment gets miscompiled,
but after making a few changes, that arithmetically are no-ops,
it can be compiled correctly.
