Hey


I'm getting SEGFAULT's using `man' sometimes. Not every manpage I try.

For example, `man man' works, so does `man 7 signal', but `man signal' gives
this when stracing it:

+++ killed by SIGSEGV +++

Anybody know why I'm getting those Out of Mem failures? I'm sure there is
enough memory (swap isn't even used at this point).

I think it's really strange.


By the way, I'm using Debian 1.3.1 with Linux-2.0.29-ISS.

thanks

Remco
