grep: Memory exhausted

[Roberto Lima]

Hi there, I use FreeBSD-4.9STABLE on my own box, and when I type "make
buildworld" on /usr/src and the system sends me the following message:

===> bin/csh/nls/ukrainian
grep 'ERR_' /usr/src/bin/csh/../../contrib/tcsh/sh.err.c | grep '^#define'
>> sh.err.h
grep in realloc(): warning: junk pointer, too low to make sense
grep: Memory exhausted
*** Error code 1

Stop in /usr/src/bin/csh.
*** Error code 1

Stop in /usr/src.
*** Error code 1

Stop in /usr/src.

My box is AMD 2400+ and 1Gb RAM DDR..
Thanks anyway
Sorry for my bad english..
