Guix,

‘readmsg’ from mailutils@3.10 segfaults on aarch64, blocking 
‘emacs’
and ‘emacs-no-x’, but not ‘emacs-minimal’.

I've been hit by this as well so I thought I'd look into it today, and I
think I found the problem! I just sent an email upstream to
bug-mailutils@gnu.org about it.

Essentially, we have a `weedc' variable that's not initialized, and on
aarch64 it gets initialized with `0xffff'. See
https://git.savannah.gnu.org/cgit/mailutils.git/tree/readmsg/readmsg.c#n469

Here's the reproducer I just sent upstream:

```
$ export MAIL=/tmp/guix-build-mailutils-3.10.drv-0/mailutils-3.10/testsuite/spool/mbox1
$ export FOLDER=/tmp/guix-build-mailutils-3.10.drv-0/mailutils-3.10/testsuite/spool/mbox1
$ ... edit readmsg script so that `gdb --args' is prepended
$ /tmp/guix-build-mailutils-3.10.drv-0/mailutils-3.10/readmsg/readmsg --no-site --no-user readmsg -h SOMETHING
...
(gdb) start

The test suite all passes if we initialize `int weedc = 0'!

Thanks,
Pierre

Cool, upstream fixed the bug! [0]

Here's a patch to apply the fix before we get the next release.

OK to commit?

Thanks,
Pierre

For easier grepping, I recommend always writing:

Otherwise LGTM, thank you!  It’s OK to push on ‘master’.
