Bug 16481

Summary:	Cpp crashes frequently
Product:	Base System	Reporter:	simonw <simonw>
Component:	gnu	Assignee:	freebsd-bugs (Nobody) <bugs>
Status:	Closed FIXED
Severity:	Affects Only Me
Priority:	Normal
Version:	Unspecified
Hardware:	Any
OS:	Any

Description simonw 2000-01-31 00:10:01 UTC

When, for example, rebuilding the kernel, cpp crashes with a variety
of signals, sometimes SEGV or ABRT, at random times. The distribution
is CDROM from cheapbytes.com.

Fix: 

setenv MALLOC_OPTIONS Z

This seems to indicate that cpp is assuming all malloced memory
is zeroed. With this fix kernel rebuilds correctly.
How-To-Repeat: cd /sys/i386/conf
config GENERIC
cd <build dir>
make depend

This usually happens due to bad RAM chips.
Can you replace them and try again?

Hmm, do you have /etc/malloc.conf?
