Description Maurice van der Pot (RETIRED) gentoo-dev

troff uses over 500MB of memory when generating the html documentation for libX11-1.3.2, causing the OOM killer to trigger on one of my systems.

Upstream has implemented a partial fix, but that fix introduces a double-free and other even nastier problems.

The patches I have attached include the upstream fix, a fix for that fix and several fixes for the most important memory leaks in troff. I've sent these fixes to the upstream mailing list as well.

Be sure to enable the new doc USE flag to libX11 if you want to reproduce this.
