Subject [jira] [Created] (QPID-3253) Unit test memory leak when compiling with clang (but not with gcc)
Date Mon, 09 May 2011 21:14:04 GMT
Unit test memory leak when compiling with clang (but not with gcc)
------------------------------------------------------------------

                 Key: QPID-3253
                 URL: https://issues.apache.org/jira/browse/QPID-3253
             Project: Qpid
          Issue Type: Bug
          Components: C++ Broker, C++ Client
    Affects Versions: 0.11
         Environment: compiling with clang 2.9
            Reporter: Andrew Stitcher


When running "make check" on the qpid c++ tree with the clang compiler valgrind reports memory
leaks in the unit_test program run, but all other tests pass:

Output of valrind is:
Valgrind error log in unit_test.vglog.
