Description of problem:
This bug does not occur on RedHat 7.1.  It has come up during our 
migration to RHEL3.  It also occurs on RedHat 7.3.

We create a shared library, libpvc.so, which gets loaded by the Sun 
java plugin in the Mozilla browser.  When we upgraded our build 
machine to RedHat Linux 7.3 or RHEL3, the plugin began to fail.  

After investigation, it was failing to load with undefined symbol 
__pure_virtual.  If we link with the same libraries on RedHat 7.1, 
__pure_virtual is defined.  

RedHat 7.1:

stpeter.ptc.com:spg [13] nm libpvc.so | grep pure
007a9c54 T __pure_virtual

RedHat 7.3 or RHEL3:

pawnee.ptc.com:spg [72] nm libpvc.so | grep pure
         U __pure_virtual



Version-Release number of selected component (if applicable):
gcc-2.96-113 (7.3) or gcc-3.2.3-20 (RHEL3)

How reproducible:
Always

Steps to Reproduce:
1. Unzip attached  ptc_pvc_test.zip 
2. cd ptc_pvc_test
3. run script "make_pvc".  This will link libpvc.so with the objects 
in the directory
4. nm libpvc.so | grep pure

    

Actual Results:  pawnee.ptc.com:spg [72] nm libpvc.so | grep pure
         U __pure_virtual


Expected Results:  stpeter.ptc.com:spg [13] nm libpvc.so | grep pure
007a9c54 T __pure_virtual
