groff and "make buildworld"

[tnhn]

Hi there,

I just synchronized and when trying to buildworld it stalled at "groff -Tascii -mtty-char -ms -o1- /usr/src/share/doc/papers/beyond4.3/beyond43.ms | gzip -cn > beyond43.ascii.gz".
The process "Troff" is taking 99% CPU but the system is not freezed, I can kill the process and he re-stalled at the next doc he try to gzip...
I'm pretty sure this is related to that : http://www.freebsdforums.org/forums/showthread.php?threadid=9395   but can't find a solution to.

Thx in advance

Leon
