So as far as I understand all that's needed to build Wine with the
new Windows-on-Windows support is to do:

  ./configure --enable-archs=i386,x86_64
  make

But then when I run WineTest I get 60+ failures instead of the usual ~16
on my machine.

https://test.winehq.org/queue/err5z_5H/report
https://test.winehq.org/queue/errloGNj/report

That does not entirely surprise me since this mode has never been tested
(neither GitLab nor the TestBot support it). But did I miss something?


For instance one failure I get is with devenum:devenum:

devenum:devenum start dlls/devenum/tests/devenum.c
devenum.c:691: Test failed: Got hr 0x80004005.
Unhandled exception: page fault on read access to 0x00000000 in 32-bit code (0x00405a75).

The reason for the crash is that wg_transform_create() in main.c returns
NULL:

     if (WINE_UNIX_CALL(unix_wg_transform_create, &params))
         return NULL;  // <---- we return NULL here

without actually calling the implementation in wg_transform.c as far as
I can see.




Here's the list of test units that fail in one of the runs. Lots of
Direct3D (but not all) and multimedia (GStreamer?) tests. Maybe there
are some quick gains to be had?
(then there's msvcrt:file which gets -2 as a file descriptor)
