While the crash may not be in winhttp, it certainly doesn't happen with the
native winhttp vs the builtin winhttp.

Anyway, I think it does happen *during* a call in winhttp.
request_send_and_receive() in winhttp/request.c calls VariantChangeType() which
eventually calls a bad memcpy().
This can be seen in the backtrace from the log:
=>0 0xf74f0d16 memcpy+0x46() in libc.so.6 (0x0100e7b8)
  5 0x7ea0a60c VariantChangeType+0x3b(pvargDest=0x100ea08, pvargSrc=0x1766c0,
wFlags=0, vt=0x2011)
[/home/ross/Downloads/wine-1.3.32/dlls/oleaut32/variant.c:982] in oleaut32
  6 0x7e2e2b0d request_send_and_receive+0x17c(request=<is not available>)
[/home/ross/Downloads/wine-1.3.32/dlls/winhttp/request.c:2879] in winhttp

Thanks for the winetricks tip.
