Description Jan Kratochvil 2009-04-16 20:48:01 UTC 
Description of problem:
Wanted to get better problems reproducibility for metacity but found out the memory mangling glibc option MALLOC_CHECK_=3 reproducively disables the option to have multiple workspaces.

Version-Release number of selected component (if applicable):
metacity-2.24.0-4.fc10.x86_64
(updated F10)

How reproducible:
Always (tried two boots).

Steps to Reproduce:
cat >/usr/local/bin/metacity <<EOH
#! /bin/sh
cd /tmp/metacity.d
ulimit -c unlimited
export MALLOC_CHECK_=3
exec /usr/bin/metacity "$@"
EOH
mkdir /tmp/metacity.d
reboot
Try to set multiple workspaces by wnck-applet.

Actual results:
wnck-applet applet still shows a single (or single column) workspace no matter how many `Number of Workspaces' you set.

Expected results:
Normal functionality as without MALLOC_CHECK_=3.

Additional info:
There will be some uninitialized memory assmed to be zero or so.

Can't reproduce on i386, might be x86_64 specific
Comment 2 Jan Kratochvil 2009-11-18 07:04:53 UTC 
Not reproducible with metacity-2.24.0-2.fc10.x86_64.
