Description Ben Woodard 2002-11-11 22:23:06 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.1) Gecko/20021003

Description of problem:
If you recompile your kernel to allow >1024 file descritors and you leave glibc
the same and then you try to use select on a file descriptor >1024 then select
corrupts memory.

It was decided that because of the unusual setup for this it really wasn't a bug
that should be fixed in glibc. However, documenting around it is probably a good
idea.

Attached is a patch to the manpage.
