I just noticed there's something wrong with my build currently,
when I test the NB today from buildbot it doesn't crash.
This issue might be caused by qt 4.5.0 which I'm experimenting

[0xc4c3384] dshow demux error: can't open video device

So, I'm in the process of switching back to qt 4.4.3 and retest.

Anyway i might found something about the destruction order (i don't
think there is race condition. CoInitialize is an atomic operation).
Could you please try with the attached patch ?
<pre wrap="">Once again my retests concludes my vlc-dshow issue isn't related to
updating to Qt4.5.0.
Anyways, FYI, I'm using gcc-3 to build vlc.
However the race condition, heap free bug is still in the dshow.cpp code.
(Introduced in the commit by your patch
I recommend someone to look at the code, and fix up some
ancient mistakes, like missing parameter for an interaction
function, which lived through the dark ages of invisibility been
pass through developer's very eyes six times..., while been through some
very useless commits like removing trailing spaces and tabs.
One way to find it is, to use a Windows XP machine with VIVO and
put vlc to run inside GDB and under qt4, Open Capture dialog, might
trigger this bug.
Below is attached debugging log file and result is from running
NB buildbot's binary, on a Windows XP machine with VIVO.
I'm confused. You said that this is a vista issue. Now are you saying
that the crash exists also in XP ?
Please attach a full debug log (vlc -v2).
And what is a VIVO exactly? Should i have special hardware to be able to check ?
In my system (XPSP3) with a sweex usb video camera and a bt73 capture
device this bug is not observed.
What are do you talk about saying "like missing parameter for an interaction
