Hello,
I am using Xerces-C 1.6 and Xalan-C 1.3 on RedHat Linux 7.1. My
application makes use of C++ STL and I get crashes at random points.
I've came to a small sample that always crashes on my system. Sample
source, compile commands and stack trace are attached below.
I am pretty sure I have a valid Xalan installation because all code
that uses Xalan but doesn't use STL streams never crashes (same for code
that uses STL but doesn't use Xalan).
Is it possible that Xalan is not compatible with STL streams? Any ideas?
