-----------------------------------

> 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:
> *** single-threaded process forked ***
