This patch works around what appears to be an optimization bug in gcc
4.5. The
symptom of the bug is that dict_pos, called from dict_lookup,
receives an
invalid value when accessing dict->used. The following ticket
describes the bug,
and includes a simple test case:

ACK. Nice sleuthing. I like this fix better than forcing the compiler to
not optimize in dict_pos since this fix makes it less likely that we get
an invalid dict->used anyway.
Just pushed as commit c17cd53d
Thanks, David. Do you mind if I push new builds to F13 and F14?
Scratch that, just F14. F13 doesn't hit this issue, of course.
