Description Daichi Kawahata 2007-05-11 23:31:09 UTC 
Hi,

My previous problem (#7294) has gone, but an another recently.
Searching similar reports in this section doesn't show the
right place to report, thus I created a new account.

When I try to open a new child window (like settings window)
from a main window already opened in a certain applications
(in this case Sylpheed, Terminal), Cairo causes a segfault
against them.

It's the latest version 1.4.7 from the git repository with;

IRIX64 6.5.30m
GCC    3.4.6 (-O2 -g -W -Wall -Wformat=2 -mips4)
GTK+   2.11.0
GLib   2.13.2
Pango  1.16.4

I'll submit the logs later.

Thanks,

Thanks for the report, a clumsy mistake on my part.

    [cairo-xlib-screen] Clear the gc_needs_clip_reset after use.
    
    After consuming the GC we need to unset the clip reset flag, so that
    if we try and get a new GC without first putting a fresh one we do not
    try to call XSetClipMask on a NULL GC.
