Xalan programs fail when compiled with -NDEBUG flag

Bad things happen when the following two conditions are met:
1. xalan-c 1.1 and xerces-c 1.4 have been compiled WITHOUT the -NDEBUG=1 flag
2. A program,which is linked against that xalan library, is compiled WITH the
-NDEBUG=1 option.

Namely, such a program will die with a SIGSEGV. It seems there is some sort of
stack problem with the passing of variable references. I am using g++ 2.95.2 on
SuSE Linux. The segmentation fault happens in the expression that's returned
from the method in #0 (below). Here is gdb output, including a stack trace, of
the dying code (note the changes in the context and executionContext arguments
between #1 and #0):
