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?

Hi Dan,

FWIW I have several exceptions when running the imagelist test.

(I also see a lot of these exceptions while I was/am debugging Skype, they are 
all DIB related).

Marcus pointed me to  X11DRV_DIB_FaultHandler

I think the exceptions are handled properly by wine, but
it might be a benign accident that the test case is causing them.

It's a DIB access exception, it's perfectly normal, it's used to trigger
a copy of the DIB bits from the X server.
