Hi,

I tried to debug this issue and found a function related to the problem. I was
unable to find the exact reason for the problem, maybe someone else has more
luck to reveal the last piece of the puzzle using my findings. However, I came
up with a workaround to prevent this problem.

When you start premiere pro 2 using +relay as debug channel, the application
works as expected but is really slow because of all the debug output. This
means that the problem is either a timing issue or related to the redirect
coded added by the +relay channel.

To verify my assumption, I added my own debug channel which does the same like
relay, but without printing any debug messages at all. The program still worked
using the new debug channel, so I limited the dlls affected by my code to find
out which one is causing the problem. Adding the relay code only to ntdll.dll
was sufficient to make premiere pro happy. I did the same with the ordinals
exported by ntdll and was able to pinpoint it to a single function:
RtlInterlockedPushEntrySList

Adding the relay code only to ntdll.dll.RtlInterlockedPushEntrySList is
sufficient to make the application start. Anyway, I was unable to find a proper
fix for this without adding the relay code. My idea that the function may need
to be hotpatchable, like the relay code, was wrong since adding
DECLSPEC_HOTPATCH to RtlInterlockedPushEntrySList did not solve the problem.

(Tested with wine-1.7.26)

Regards,
Michael
