Subject: 23.3; Segfault on opening 'woman' on 'wget'
Date: Tue, 23 Aug 2011 10:55:08 +0200

Emacs segfault when :

1- run emacs -Q
2- M-x woman <ENTER> wget <ENTER>

"Fatal error (11)Segmentation fault"

In gdb, I tried to execute `bt full' but no table info is available. I
also tried `xbacktrace' as advertised in M-x report-emacs-bug but this
is an undefined command.

I'm using the default emacs23 coming with Ubuntu natty.

Thank you for taking care of Emacs

Can't do anything without a backtrace. Does Ubuntu provide a debug
package, or can you compile Emacs from source with debugging info? The
latter goes something like:

sudo apt-get build-dep emacs23
extract emacs source, and run

CFLAGS="-O0 -g" ./configure
make
cd src
gdb ./emacs
run -Q
repeat creash, post backtrace

when I follow this process, I get the sources for 23.2.1 and I can't
reproduce the crash. I don't know where the 23.3.1 version of the
binary I used come from (I'm sure I never compiled it myself).

You should probably close this report, sorry about that.
