JCK: QuickSilver api test fails with -Xprof flag

When running the JCK13 runtime tests on Quicksilver - one api test fails:
api/javax_swing/SwingUtilities/descriptions.html#other

uname -a
Linux static 2.4.19-4GB #1 i686 unknown


Running this test with the -Xprof flags returns the error:
Assertion `(*__errno_location ()) == 0 && count == (size_t) size' failed.


The test passes when the -Xprof flag is left out.

To run the test, set JAVA_HOME to the relevant jdk/jre.
export CLASSPATH=/net/latte.ireland/export/home4/jck/JCK-runtime-13a/classes:/net/latte.ireland/export/home4/jck/JCK-runtime-13a/javatest.jar
