Source code causing the core dumps when linked with Xerces none

Description Martin Frydl 2001-10-23 17:31:14 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/4.77 [en] (X11; U; Linux 2.4.5 i686)

Description of problem:
I have a simple program throwing and catching the exception. Alone it works
fine, but when I link it with Xerces-C++ library it dumps core. The program
itself in fact does not need the library.

I use precompiled Xerces 1.5.1 from
http://xml.apache.org/dist/xerces-c/stable/ It was compiled on RedHat 6.1
with egcs-2.91.66 and glibc-2.1.2-11 (from Xerces-C++ FAQ on
xml.apache.org/xerces-c)

I do this:
Works:
	gcc -o test test.cpp
Compiles, but segfaults when run:
	gcc -o test test.cpp -lxerces-c1_5_1

I'm using gcc-2.96-85 from latest updates.


Version-Release number of selected component (if applicable):


How reproducible:
Always

Steps to Reproduce:
1.Compile using gcc -o test test.cpp -lxerces-c1_5_1
2.Run it

You cannot mix code compiled with different C++ compilers.
Either all libs and main program have to be compiled with egcs 1.1.x, or
gcc 2.95.x, or 2.96-RH, or 3.0, or 3.1, no mixing is possible.
