Hi,
on my machine it happens with IMAP server _on localhost_.
A how-to-reproduce procedure here is:
- open inbox in browser
- open first mail
- click "next mail"
- proceed with clicking "next mail" (thereby stepping
through mailbox mail by mail), until segfault happens.
Sometimes it takes a while, but il WILL happen sooner or
later.
- now, reloading will trigger the segfault again and again.
- viewing the next mail and going back shows the mail
without segfault. This also allows to continue to use
squirrelmail until the next segfault is encountered.

Sadly I still get a segfault with a fresh CVS copy :-(

This seems to be a duplicate of bug #38265.
Dmitry has committed a patch for it several minutes ago, please try the
next snapshot (or CVS sources).
Thanks.

No, using IMAP server on a different machine didn't change anything. It
still works fine without any crashes.

ok. I now checked a fresh copy from the cvs, and reduced my php
installation to the really minimum to run the offended app that
crashes.
my configure line now is :
./configure --enable-debug --with-pcre-regex --with-iconv
--enable-session --disable-all --with-libdir=lib64 --with
-apxs2=/usr/sbin/apxs2
results :
imap server in remote === RANDOM CRASH
imap server in localhost === NO CRASH.
the gdb and valgrind info are the same.
