Bug#616389: xserver-xorg-video-radeon: Crashes when closing graphical VT ("(EE) RADEON(0): failed to set mode: Permission denied")

[Thue Janus Kristensen <thuejk@gmail.com>]

Thanks to the gdb guru :).

With both�drmDropMaster breakpointed in the second server, and�drmSetMaster breakpointed in the first server,�drmDropMaster is called first in the second server, and the first server doesn't reach drmSetMaster until after I continue the second server from the drmDropMaster�breakpoint. No crash.

With only�drmSetMaster breakpointed in the first server, but the second server still running with gdb attached for consistency, there is no crash when I continue the first server from the�drmSetMaster breakpoint.

With both servers running inside gdb, but no breakpoints, it crashes.

Yes, you want 'handle SIGPIPE nostop noprint' in gdb.
