Description

Rational Purify is complaining about memory write overruns: Here is some sample output:

ABW: Array bounds write
This is occurring while in:
xercesc_3_0::XMemory::XMemory() [libxerces-c.a]

Writing 1 byte to 0x148341c in the heap.
Address 0x148341c is 1 byte past end of a malloc'd block at 0x1483410 of 12 bytes.
This block was allocated from:
malloc [rtlib.o]

{ => memptr = ::operator new(size); }

catch(...) {

xercesc_3_0::XMLMutexMgr*xercesc_3_0::XMLPlatformUtils::makeMutexMgr(xercesc_3_0::MemoryManager*const) [PlatformUtils.cpp:702]

This only occurs on a Sun Sparc using SunPro CC 5.0. Xerces works fine on Linux and Windoze. This is from the 3.0.0 tarball build.
