Nope, using "-O0" doesn't help.  (I only tested this with Solaris, I
don't currently have a OpenBSD/sparc box running at the mo.)

I've no idea whether the bug was reported.  I went looking on the gcc
mailing lists for info, but did not find any specific reference to
imap.  But then maybe I didn't look hard enough.

Looking at the code, it's a bit scary...  But I've found a fix!!!

I hope it does the right thing...  Let me know what you think!

Cheers,


Duncan.
