Bug ID: 40384
Summary: dinput8:dinput regression caused by new compiler
Product: Wine
Version: 1.9.6
Hardware: x86
OS: Windows
Status: NEW
Severity: normal
Priority: P2
Component: directx-dinput
Assignee: wine-bugs at winehq.org
Reporter: fgouget at codeweavers.com
The WineHQ upgrade changed the cross-compiler used to generate the reference
WineTest executables. Since the upgrade the dinput8:dinput test has these
failures on all 32 bit Windows platforms:
dinput.c:519: Test failed: EnumDevicesBySemantics did not call the callback
hr=80070057
dinput.c:520: Test failed: EnumDevicesBySemantics should enumerate the keyboard
dinput.c:521: Test failed: EnumDevicesBySemantics should enumerate the mouse
dinput.c:527: Test failed: EnumDevicesBySemantics failed hr=80070057
dinput.c:535: Test failed: EnumDevicesBySemantics failed hr=80070057
dinput.c:536: Test failed: There should be devices available before action
mapping available=0
dinput.c:543: Test failed: EnumDevicesBySemantics failed: hr=80070057
dinput.c:548: Test failed: EnumDevicesBySemantics failed hr=80070057
dinput.c:554: Test failed: EnumDevicesBySemantics failed: hr=80070057
dinput.c:559: Test failed: EnumDevicesBySemantics failed hr=80070057
dinput.c:565: Test failed: EnumDevicesBySemantics failed hr=80070057
dinput.c:571: Test failed: EnumDevicesBySemantics failed hr=80070057
dinput.c:577: Test failed: EnumDevicesBySemantics failed hr=80070057

I can reproduce the problem with this compiler:
$ i686-w64-mingw32-gcc --version
i686-w64-mingw32-gcc (GCC) 5.3.1 20160205
But if I recompile the tests with -O0 the failures go away which points to a
compiler bug.
We need to either:
* Switch to a non buggy compiler to build the reference WineTest executables.
(which might involve reporting the bug in the first place)
* Add 'CFLAGS = -g -O0' to the test's Makefile.in as a workaround.
(preferably once we can point to a relevant compiler bug)
* Find some other nicer workaround in the C file.
