SetThreadAffinityMask() regression spotted in Wine 1.2-rc6. The bug 19982 was
fixed one day, but it returned back in RC6.
Test utility can be downloaded here: http://rh-software.com/downloads/siv.zip
Normally the command:
$ wine siv -save=[processors]=stdout -nodriver 2> /dev/null | egrep "(CPU-|IC 
G)"
returns output:
                       MPS  MCP  HTT  APIC  G  N  Affinity       Speed
Processors  |P| CPU-0  0    0    0    0000  0  0  0x00000001   3.17GHz
            |C| CPU-1  0    1    0    0001  0  1  0x00000002   3.17GHz
but sometimes it returns:
                       MPS  MCP  HTT  APIC  G  N  Affinity       Speed
Processors  |P| CPU-0  0    0    0    0000  0  0  0x00000001   3.17GHz
            |P| CPU-1  0    0    0    0000  0  1  0x00000002   3.17GHz
which is incorrect.
