Done. The crash came back and here's the result:

       1 [main] bclanc 2544! C:\budcat\tools\bin\bclanc.exe: *** fatal 
error - could not load C:\Windows\system32\ws2_32.dll, Win32 error 998
Stack trace:

The path is correct. I have no explanation why changing from a filename 
to a pathname (and LoadLibrary to LoadLibraryW) would make any 
difference, unless there's a race condition, say if LoadLibrary[W] is a 
bit faster when you give it a full path. That's just speculation, of 
course. But the intermittent nature of this crash (1 in 500ish 
invocations) would also seem to point to a race condition of some kind.
