Still stumped... Re: What do you guys make of this?

[Sylvain Petreolle]

I think it can be possible.

One month ago I notice that winedbg has problems when reading the
process memory it tries to acess.
Let me show the problem I encounter :
- the windows program launched causes some error;
- winedbg launches;
- it tries to read a memory that is out of bounds;
- a 2nd winedbg launches, trying to debug the first;
- same error occurs (out of bound read);
- a 3d winedbg launches, being successfull to read the memory of the
2nd.

Conclusion:
Only wine code is used. (I defined all dll's built-in, and only
advapi32 is loaded when using winedbg)
