I think this may be going slow since the "right people" are not experiencing 
this problem, and are therefore unable to try to fix it.

I'm still looking into it, since I have at least a minimal amount of 
experience toying with winedbg and my wine exhibits the problem, but of 
course I am a bit out of my depth with some of this stuff, and the fact that 
gdb doesn't work for me isn't making it any easier.

Here's the latest I know, after spending very little time, so far, looking 
into it:  First, the routine which Eric suggested I start my research with 
(DEBUG_ProcessElfObject), is not called, except for the wine executable 
itself.  That is, DEBUG_ProcessElfObject is never called for any .dll.so 
files whatsoever.  Secondly, in the case of the wine executable (by this I 
mean the "wine" file) DEBUG_ProcessElfObject fails to find symbols, as 
DEBUG_ProcessElfFile returns DIL_NOINFO (I'm not sure why, yet).

Is it possible that the latter problem causes the former?  That is, if "wine" 
is not found to contain debug symbols, will winedbg stop trying to load 
symbols for native wine libraries?

Barring that, I ought to try to determine why it never runs... but I'm a bit 
confused as to how winedbg ever ends up at DEBUG_ProcessElfObject in the case 
of a library.  Could someone with a working winedbg show me a stack trace at 
the point where winedbg calls DEBUG_ProcessElfObject for a .dll.so library?  
This might help me to figure out where my wine diverges from the expected 
execution path.

Wish me luck.  Depending on the complexity of the root cause I may just not 
have what it takes, but I'm happy to patiently plod forward until I hit a 
brick wall, as this situation is making it difficult for me to work, as well.
