Impact Assessment
Impact Description

This is a maintenance release of IBM XL C++ Runtime for AIX 12.1. It contains fixes for client-reported and internally found defects.

Test Results


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 issues to report.
