It's impossible to say from gdb's output what's at fault here, but
changing the optimization switches should not alter the program's behavior
like this..

This is a setup problem, unrelated to the problem you've had with logging
in. What path do you use for your Maildirs, and how have you set up Binc
IMAP?

I bet you wouldn't notice any difference from using a plain old -O2 and
the most optimal switches you showed above. Binc IMAP's parser is the only
place where optimization has any noticable effect, but that's more on the
algorithmic side and less on the unroll-align-peep optimization side.
