+Status: Bogus
Bug Type: Reproducible crash
Operating System: MDK 8.2 (Linux 2.4)
PHP Version: 4.3.2
New Comment:
Why do you add --with-imap-ssl if the c-client is not build with SSL
support? Not PHP bug.

gdb version: GNU gdb 5.1.1 (via RPM on Mandrake 8.2)
IMAP is imap-2001a via RPM on Mandrake 8.2. openssl is openssl-0.9.6c,
again via RPM on Mandrake 8.2. There is no other version of openssl on
the box.
I have verified that it is the imap_ssl option; with just imap apache
starts okay.
PHP 4.3.0 works fine on the same servers. On the servers that I've
done testing on so far IMAP is not actually used, so there isn't a
c-client configuration per se that I am aware of. It isn't that apache
dies when using IMAP; it segfaults very quickly during startup.
Thanks, glad to help debug as needed...

What GDB version are you trying with..?
Also, how was the c-client configured ?
Are you absolutely sure it's using the same openssl library
you're linking PHP with (--with-openssl) ??

With --enable-debug, gdb gives this error:
==========================================================
Program received signal SIGSEGV, Segmentation fault.

==========================================================
On a hunch, given the dl*.c file name, I pulled out the two imap
options and apache now starts / runs.
--with-imap \
--with-imap-ssl \

Try with --enable-debug and generate new GDB backtrace.
(NOT strace)
And try find out what configure option is causing this.
Remove them one by one until it works..

The following bug is reproduceable on two different systems. As soon
as the process starts it cores. A gdb stack trace and the tail of an
strace of the bug is below, as is the php configure script options.
The same configuration works fine with 4.3.0.
Program received signal SIGSEGV, Segmentation fault.
