            Bug ID: 48054
           Summary: gdi32:bitmap fails on Windows XP and 2003
           Product: Wine
           Version: unspecified
          Hardware: x86
                OS: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: gdi32
          Assignee: wine-bugs at winehq.org
          Reporter: fgouget at codeweavers.com

gdi32:bitmap started failing on Windows XP and 2003 right after the winehq.org
upgrade:

bitmap.c:1015: Test failed: StretchDIBits failed for 32/62/0/0
bitmap.c:1023: Test failed: GetDIBits failed for 32/62/0/0
bitmap.c:1052: Test failed: StretchDIBits failed for 32/62/0/0
(repeated 12 times)

See http://winetest.dolphin/data/tests/gdi32:bitmap.html
See also the attached screenshot showing the failures did start on Sept 09.

And this wine-devel thread:
https://www.winehq.org/pipermail/wine-devel/2019-October/152082.html

The failures are systematic and happen on all machines running one of these two
Windows versions. What's strange is that the TestBot's wxppro and w2003std VMs
have not been modified in this timeframe and neither has the gdi32:bitmap test.

In fact this appears related to the compiler which would explain why the
failure started when winehq.org (which builds the official WineTest binaries)
was upgraded to Debian 10.

Specifically, letting wtbbuild, which still runs Debian 9.9
(i686-w64-mingw32-gcc 6.3.0 20170516), compile the test binaries results in no
failure:
https://testbot.winehq.org/JobDetails.pl?Key=59354

But using a binary compiled with i686-w64-mingw32-gcc 8.3-win32 20190406 (in
this case on my development machine) produces the 36 failures:
https://testbot.winehq.org/JobDetails.pl?Key=59355

Either that or it's quite possibly a result of the new everything-as-PE vs. the
old cross-compilation approach still used by wtbbuild.
