bug#15344: 24.3; Crash when yanking in c-mode

[Lars Ljung]

This bug report will be sent to the Bug-GNU-Emacs mailing list
and the GNU bug tracker at debbugs.gnu.org.  Please check that
the From: line contains a valid email address.  After a delay of up
to one day, you should receive an acknowledgment at that address.

Please write in English if possible, as the Emacs maintainers
usually do not have translators for other languages.

Please describe exactly what actions triggered the bug, and
the precise symptoms of the bug.  If you can, give a recipe
starting from `emacs -Q':

Emacs crashes with segmentation fault. Follow these steps to reproduce:

1) Run emacs -Q
2) Open new buffer in c-mode
3) Enter this:

int test(int *p);
#define TEST(p)

4) copy the first line and yank it at the end of the second line
5) Segmentation fault

The backtrace is attached.


If Emacs crashed, and you have the Emacs process in the gdb debugger,
please include the output from the following gdb commands:
    `bt full' and `xbacktrace'.
