Hi Kieran,

You've got it. Notice how the output is prefixed with the pid of the
wine process; that's valgrind's output. The source code lines on the
end of the line, like a backtrace.

So that output shows that there's a leak in atl100, allocated via
heap.c's notify_alloc, then RtlAllocateHeap, then IOCS_Create, then

Your task would be to find that leak, then fix it, i.e., free the
memory where it should have been, but wasn't.

FYI, after running the tests, you may need to run 'rm service.ok',
otherwise the test won't run (only if it succeeded beforehand).
