>Description:
I get the following failures in the libjava testsuite, see: http://gcc.gnu.org/ml/gcc-testresults/2002-04/msg00935.html

FAIL: Throw_2 execution from source compiled test
FAIL: Throw_2 execution from bytecode->native test
FAIL: Throw_2 -O execution from source compiled test
FAIL: Throw_2 -O execution from bytecode->native test

Running the Throw_2 executable left behind by the harness under gdb, I get:

State-Changed-Why:
    You need to continue further in your GDB session.
    The SIGSEGV is perfectly normal and is a part of Boehm-GC
    initialization.
    This is a FAQ
