Description

On AIX, when compiled with XLC++, the test 22.locale.num.get.mt.cpp fails with a SIGABRT. This failure is not likely to be an indication of a thread safety problem because it happens consistently for non-reentrant builds.

This is a new test for 4.2.1, so it is considered a regression.
