Profiling?

How to profile wine? The =C2=ABwine-wiki=C2=BB recommends to use =C2=ABopro=
file=C2=BB,
however it seems to work wrong.

E.g. if I profiled an app with =C2=ABoperf -gc /tmp/a.exe=C2=BB, then as I
understand I should get results of calls to wine dlls with =C2=ABopreport
--callgraph --symbols /tmp/a.exe=C2=BB. However I can get only results for
=C2=ABwine-builder=C2=BB. But as I understand, these results irrelevant, ar=
en't
it?

I don't even know what to do. Wine is the latest, compiled with
debugging symbols.
