Impact Assessment
Impact Description

This is a maintenance release. It contains fixes for client-reported and internally found defects.


Regression: An error in the Maintenance Delivery Vehicle (MDV) that produces incorrect or unexpected behavior causing a supported feature to stop functioning as designed.
This includes:

  • Coding errors that cause a regression
  • Documentation or packaging problems that cause a regression
  • Errors reported in a new function delivered in a MDV that cause a regression

Incomplete: An error in the MDV has not regressed, but does not work as designed.
This includes:

  • Fixed APARs which did not solve the original problem but did not break anything new
  • APARs reporting documentation errors, such as readme errors, that cause problems applying an MDV but do not lead to a regression

  • Regression and incomplete APARs are considered fix-in-error or MDV-in-error
  • Definitions above apply only to valid APARs that result in product fixes (APARs returned as working-as-designed are not assessed for being fix-in-error)
  • Issues in major releases due to new functionality do not apply in this definition

There are no known regressions to report.

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. To save time, know the answers to these questions:

  • 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.
