I am using the new "newsticker tree view" under GNU/Linux and GTK+
2.8.11. Very often I get a segmentation fault in the function
update_frame_tool_bar. The core file list the following backtrace (at
the end of the message there is the "bt full" listing):

Is this still an issue in Emacs 23 or 24?

More information was requested, but was apparently not given, so I'm
closing this bug report. If this is still a problem, please reopen the
bug report.

Could you do two things:
1. Recompile without optimization (CFLAGS="-g" ./configure; make)
2. Trigger the crash again, and in gdb, do
f 3'
p stock
xstring
Please give the results, as well as the new backtrace. Thanks.

Without optimization the problem disapears. See too bug number 601.

Looks like a compiler bug. Upgrading to a newer version of gcc might
fix it.

In 90% of the cases, if a program crashes when compiled with
optimization but runs fine when compiled without optimization, the
problem is actually not a compiler bug. It's just that the C language
has many "undefined" behaviors, and programmers tend to assume a lot
more than the language actually guarantees.
