-----------------------------------
Resolution: Won't Fix
> 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
> Priority: Major
>
> 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."
> Stack trace in crash report:
> Application Specific Information:
