Helpful Hints For Obtaining Technical Assistance:

Before you contact IBM XL Compiler Support, gather the background information that you need to describe the problem. When you describe a problem to an IBM software support specialist, be as specific as possible and include all relevant background information so that the specialist can help you solve the problem efficiently. To save time, know the answers to these questions:

Can the issue be reduced to a small test case?
- Review technote 1084174: Test Case Reduction Techniques for details.
Can the test case be provided to IBM?
- Review technote 1260804: Test case preparation for IBM XL compilers support for details.
What compiler version and fix pack level were you using when the problem occurred?
- This can be found by compiling with the -qversion=verbose compiler option.
Do you have logs, traces, or messages that are related to the problem?
Can you reproduce the problem? If so, what steps and compiler options do you use to reproduce it?
Is there a workaround for the problem? If so, be prepared to describe the workaround.

If you have helpful information to diagnose or identify the problem on your system, you can provide this data by following the instructions to exchange information with IBM Technical Support.
