Re: [gentoo-dev] xemacs segfault : it's not over yet

Howdy,

See Comment 8 at http://bugs.gentoo.org/show_bug.cgi?id=1501

The xemacs segfaults you are seeing seem to be related to sandbox. This
is a problem that is being currently researched by gentoo developers. In
the mean time, there are two work-arounds:

1. If you have a segfaulting xemacs you can run xemacs like this to
avoid the segfaulting:

   LD_PRELOAD=/usr/lib/portage/lib/libsandbox.so xemacs

Better yet, define yourself an alias:

   alias xemacs='LD_PRELOAD=/usr/lib/portage/lib/libsandbox.so xemacs'

2. If you feel like re-emerging xemacs, temporarily change the
FEATURES="..." line in /etc/make.conf from "sandbox" to "-sandbox". Then
"emerge xemacs". The resulting xemacs binary should no longer segfault.
At this point you can restore your old FEATURES="..." line in
/etc/make.conf to include "sandbox" (a good idea).

eg. If my FEATURES line looks like:

    FEATURES="sandbox digest noclean"

then I change it to:

    FEATURES="-sandbox digest noclean"

then "emerge xemacs", then change back to 

    FEATURES="sandbox digest noclean"

Then run xemacs as you normally would (ie. no LD_PRELOAD setting
required).
