FreeBSD stepney 3.4-RELEASE FreeBSD 3.4-RELEASE #0: Sun Jan 30 15:35:07 PST 2000     simonw@stepney:/usr/src/sys/compile/STEPNEY  i386

>Description:
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.


>How-To-Repeat:
cd /sys/i386/conf
config GENERIC
cd <build dir>
make depend

>Fix:
setenv MALLOC_OPTIONS Z

This seems to indicate that cpp is assuming all malloced memory
is zeroed. With this fix kernel rebuilds correctly.
