Apache fails to load libphp4.so when openssl and cURL is
enabled. It
works, if one of them is disabled.

This report is probably a duplicate of 10990.

RedHat 7.0.1 (glibc 2.2)
Apache 1.3.20
Mod-SSL 2.8.4
OpenSSL 0.9.6
cURL 7.7.3 (ipv6 and openssl support enabled)

(my cURL lib includes openssl support. 10990 uses imap w/ ssl
support. It is the cause probably - Not verified.)


== When both openssl and curl is enabled ==
