  • 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.
  • Can a source test case be provided to IBM? Can the issue be reduced to a small test case?
  • 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.
