Internal Error: Segmentation Fault during build

While building Xalan-C 1.5 on Redhat with Xerces-C 2.2.0 installed, I
encountered the following:
During the build of XPathExecutionContextDefault.o, I get:
In method 'xalanc_1_5::XPathExecutionContextDefault(xalanc_1_5::XPathEnvSupport &,
xalanc_1_5::DOMSupport &, xalanc_1_5::XObjectFactory &, xalanc_1_5::XalanNode *,
const xalanc_1_5::NodeRefListBase *, const xalanc_1_5::PrefixResolver *)':
/students/elddm/xalan-c/src/Include/XalanObjectCache.hpp: Internal error:
Segmentation fault.

The build cannot proceed past this point.
