Bug ID: 40385
Summary: usp10:usp10 regression caused by new cross-compiler
Product: Wine
Version: 1.9.6
Hardware: x86
OS: Windows
Status: NEW
Severity: normal
Priority: P2
Component: usp10
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 usp10:usp10 64 bit test has this
failure on Windows Vista to Windows 10:
usp10.c:3087: Test failed: ScriptStringCPtoX should return E_INVALIDARG not
00000000
See:

https://www.winehq.org/pipermail/wine-devel/2016-March/112371.html
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.
