Extended Description
Dragonegg can compile wine successfully, aside from http://bugs.winehq.org/show_bug.cgi?id=28050. Running its test suite, however, shows a few problems. This is the fourth one.
To reproduce, compile wine with:
$ CC=llvm-gcc ./configure
$ make
then run the test:
$ cd dlls/user32/tests
$ make win.ok
this will fail:
austin@debian:~/wine-llvmgcc/dlls/user32/tests$ make win.ok
win.c:5032: Test failed: creation failed err 0
win.c:5034: Test failed: invalid rect right 0
win.c:5035: Test failed: invalid rect bottom 0
win.c:5044: Test failed: creation failed err 0
win.c:5046: Test failed: invalid rect right 0
win.c:5048: Test failed: invalid rect bottom 0
compiling dlls/user32/win.c with gcc-4.5 with gcc, or using -O0 instead works around the issue. I'll attach preprocessed source files from draognegg and gcc (versions below). If more info is needed, please don't hesitate to ask.
