Thomas Quinn commented on XERCESC-1578:
---------------------------------------

I also ran into this problem on an OSF1 V5.1 alpha box.  Both cxx (Compaq C++ V6.5-040 for Compaq Tru64 UNIX V5.1B (Rev. 2650)) and gcc v. 3.4.0 give SEGVs.

The following patch fixes the problem for me.   My guess is that the original intent was to use the XMemory overload of the new operator, but RecursiveMutex is not derived from XMemory.
