Can you try that again, but when you hit the segfault,
type the following commands into gdb:
up
print locale
print pce
print pce->locale

Still getting the segfault at almost the same place. Seems a lot
easier to reproduce now.
Program received signal SIGSEGV, Segmentation fault.

hello!
i have nearly the same problem...
i've wondered, that sometimes are segfaults in the error_log. i have
installed
the newest php (4.2.3) & apache (1.3.26) version.
now i have found a cause:
if this in the mail header:
From: ()
imp shows as sender. with the attempt to open the email, the
apache-
process segfaulted. after some try, i could fetch a strace-log from the
process.
you can found it here: http://dpits.de/segfault.log
thank you!
bye

I upgraded from 4.1.2 to 4.2.3 yesterday and have seen many seg faults
in the error_log when I came in this morning.
I am using Apache 1.3.26, mod_ssl 2.8.10, Openssl 0.9.6g, Compaq Tru64
4.0G.
My PHP configure is pretty basic:
./configure --with-mysql --with-imap --with-curl --quiet
--with-apxs=(path_to_apxs)
We, also, are using IMP (2.2.7). I have not tried to produce the
seg-faults

I'm encounting this same bug using Horde/IMP/Turba (2.1/3.1/1.1) on Red
Hat 7.3 with all updates (except mm-1.1.3-8 which seems to cause
problems with Apache restarts) and here's what i've tried:
- compiling Apache (1.3.26), PHP (4.2.3), and mod_ssl (2.8.10) without
mm support
- compiling PHP 4.2.3 without mm support and using the pcre library
packaged with Red Hat
- downloading a fresh pcre library (v3.9) and compiling PHP against
that.
- compiling everything with mm support and external pcre library (3.9)
In each case the same segfault occurs.
If i compile the software (Apache, mod_ssl, PHP) with debugging symbols
i can't get the segfault to occur. Been through about 300 test
messages and it still hasn't segfaulted.
This is driving me nuts.
