Try bisecting in optimization flags. Assuming -O1 works, find out which optimization flags are on in -01 vs. -O2, and turn half of those on, etc.
Funny you mention that - I am compiling wine with -O1 right now ;)
..and yes, after that i will go through the different flags and see if i can find a culprit.
I'll report back when i am done (this may take a while).
