OSX 10.5 (Leopard): Xerces uses CoreFoundation library calls and crashes...
---------------------------------------------------------------------------
Key: XERCESC-1780
URL: https://issues.apache.org/jira/browse/XERCESC-1780
Project: Xerces-C++
Issue Type: Bug
Components: Miscellaneous
Affects Versions: 2.8.0
Environment: MacOS X 10.5 Server (Leopard), i386 or x86_64
architecture.
Apache 2.2.6, Prefork, non-threaded, 64bit (default OSX 10.5 httpd server)
Reporter: Valery Tschopp
The Shibboleth apache2 module (see http://shibboleth.internet2.edu) uses the
Xerces-C library to process XML messages.
When the module is loaded by apache2, the shared Xercecs-C library is loaded
too and initialized.
At initialization, first some error messages appear, then the whole httpd
process crashes.
Error messages in /var/log/apache2/error_log (a lot of them):
"The process has forked and you cannot use this CoreFoundation functionality
safely. You MUST exec().
Break on
__THE_PROCESS_HAS_FORKED_AND_YOU_CANNOT_USE_THIS_COREFOUNDATION_FUNCTIONALITY___YOU_MUST_EXEC__()
to debug."

It look like that Apple changes something with OSX 10.5. As soon as a process
fork, you a not allowed to use CoreFoundation library calls anymore...
