imagelist test exception?

[Dan Kegel]

comctl32/tests/imagelist.c seems to throw an exception
during GetDIBits(), but for some reason, the test continues
and succeeds (except in Valgrind, which is why I noticed).
Do other folks also see a seh exception in the +seh log
on this test?

I narrowed the test case down a bit (see patch).
Can anyone clue me in on what's going on here?
