Subject [jira] Created: (STDCXX-587) purify reports memory leak from __rw_tmpbuf in 20.temp.buffer.mt

purify reports memory leak from __rw_tmpbuf in 20.temp.buffer.mt
----------------------------------------------------------------

                 Key: STDCXX-587
                 URL: https://issues.apache.org/jira/browse/STDCXX-587
             Project: C++ Standard Library
          Issue Type: Improvement
          Components: Tests
            Reporter: Travis Vitek
            Priority: Minor
             Fix For: 4.2.1


Each test thread iterates some number of times switching on a counter. If the last iteration
runs one of the allocation functions, the temporary buffer will not be deallocated when the
thread exits.

Purify: Searching for all memory leaks...

Memory leaked: 42 bytes (6.98%); potentially leaked: 0 bytes (0%)
