My test server works fine, but my production server gets segmentation
faults during SSL negotiation, though it worked for a while last week.

As far as I can tell, both systems are built using the same modules.
(openssl-0.9.7b, curl-7.11.0, php-4.3.4)

The URL runs OK from the command line with curl, but not from php/libcurl.

Here's the output I get from verbose mode:

* About to connect() to certification.authorize.net port 443
* Connected to certification.authorize.net (64.94.118.140) port 443
* successfully set certificate verify locations:
* CAfile: /usr/local/share/curl/curl-ca-bundle.crt
 CApath: none
Segmentation fault

Here's what I get from the development site:

* About to connect() to certification.authorize.net port 443
* Connected to certification.authorize.net (64.94.118.140) port 443

HTTP requests are working, just not HTTPS.
I'm running out of things to try. Suggestions?
