wine's conformance test kernel32/thread.ok always fails/crashes on ubuntu 11.10

[Dan Kegel]

I'm building wine from git on a freshly installed, up to date ubuntu 11.10 beta 2.
kernel32/thread.ok fails reliably for me, on both an i7 and an i5,
whether or not I use taskset to restrict it to a single core. Log:

cd dlls/kernel32/tests
make thread.ok
...
Protocol error:003b: partial read 12
wine client error:3a: read: Bad address
err:seh:raise_exception Unhandled exception code c0000005 flags 0 addr
0x690abb19

The errors vary, but there's always a bad file descriptor, and often
a crash. (Sometimes starting a wineserver in the foreground fails
because trying to get the /tmp/.wine-.../lock fails with EAGAIN, too,
so I think wineserver is also deeply unhappy.)

Also filed as http://bugs.winehq.org/show_bug.cgi?id=28640
since it's not clear if it's a wine bug, an ubuntu bug, or a kernel bug yet.

Was using default gcc (Ubuntu/Linaro 4.6.1-9ubuntu3) 4.6.1,
recompiling just kernel32 with gcc-4.5 made the error go away.

So it's a wine bug and/or a gcc bug...

There is at least one gcc problem report related to wine in debian,
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=641056
though I have no idea if it's related.

Need to force the package to build with gcc-4.5 then.

[Dan Kegel (dank)]

Might be the change in gcc defaults, see http://bugs.winehq.org/show_bug.cgi?id=28753

This is fixed in the wine1.4 packages. Closing the old bug tasks.
