Debugging wine/windows applications

[John Yani]

I tried to run wine under gdb and failed. Using multiprocess gdb I
endup with weird trace:

0xf7ffd430	
0x7bc846f9	
0x7bc8480f	
0x7bc84855	
0x7bc42a94	
0x7bc433b1	
0x7b8772f7	
0x7ebab89b	
0x7bc80014	
0x7bc8005d	

Where 0x7****** addresses are not connected to any module. And
0xf****** addresses are from /lib/ld-linux.so.2, debug symbols for
which I can't find.
Can somebody explain what's hapenning?

Running wine with winedbg under gdb fails with message
"err:module:LdrInitializeThunk Main exe initialization for
L"C:\\windows\\system32\\notepad.exe" failed, status c0000022"

Is there any tutorial on how to run wine with applications under gdb?
