Summary: wine segffaults on Linux kernel 2.6.18 and noexec
                    enabled
           Product: Wine
           Version: CVS
          Platform: PC
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: major
          Priority: P2
         Component: wine-binary
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

On linux kernel 2.6.18, i386 and x86_64 platforms, running with noexec feature 
enabled (the default), a lot of windows apps cause wine to segfault or crash. 
Booting Linux with noexec=off boot param makes the apps to work again. In 
2.6.17 and earlier, they work even with noexec=on. There is probably a massive 
stack corruption because it's not possible (at least for me) to get a valid 
backtrace, even with a fully debug-enabled wine.
