           Summary: Wine is not data-race detector friendly
           Product: Wine
           Version: 1.2
          Platform: x86
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: wine-bugs at winehq.org
        ReportedBy: bart.vanassche at gmail.com


Running Wine under a data-race detector triggers huge numbers of data-race
reports on Wine functions. This makes it impossible to analyze data races in
application that are running under Wine with Valgrind. An example (Valgrind
trunk r11292):

$ valgrind --trace-children=yes --vex-iropt-precise-memory-exns=yes
--gen-suppressions=all --tool=drd --show-confl-seg=no wine notepad
