INFORMIX SERVER / 5725A3900 / C10 - IDS 12.10 |
| Problem description: |
Problem was reported in a special build of 12.10.FC9W1 on sol64
and the test case that I created
confirms the problem reproduces on linux x86_64 running
12.10.FC9W1 and 12.10.FC12W1.
Upon failure the a sample stack from a 121.10.FC12W1 server on
linux x86_64 will look like:
