[Bug 24401] New: WoW segfault on login, Starcraft 2 segfault on startup (Ubuntu 10.10)

http://bugs.winehq.org/show_bug.cgi?id=24401

Summary: WoW segfault on login, Starcraft 2 segfault on startup
                    (Ubuntu 10.10)
           Product: Wine
           Version: 1.3.2
          Platform: x86-64
        OS/Version: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

In ubuntu 10.10 WoW segfaults after I login. Starcraft 2 also segfaults the
same way, but on startup.

To reproduce:
echo 1 | sudo tee /proc/sys/kernel/yama/ptrace_scope

(this is the default in Ubuntu 10.10 AFAIK)

The following message shows up in dmesg:
[ 1994.869982] ptrace of non-child pid 8718 was attempted by: wineserver (pid
8543)

Workaround:
echo 0 | sudo tee /proc/sys/kernel/yama/ptrace_scope
