busybox segfaults (but is it busybox?)

Hi!

I'm using kernel 2.4.20, Busybox 0.60.5 and uClibc 0.9.19.
These are all compiled using the latest root_fs building system.
The target stuff is run on an AMD elan-520 processor with 32 MB RAM.

All goes well during startup, but if an insmod fails, it segfaults.
As a matter of fact, *every* failure (thus not just insmod) crashes the 
shell and its parents...
This is not good.

It is also the case if I boot from the Linux-Bootable Business Card 
CD-ROM and then chroot to /dev/hda1. busybox segfaults on error and I 
leave the chroot...

I can't find any info on this on the mailing lists and I'm at a loss on 
where to start debugging this... Is it Busybox or is it uclibc or ???

Any hints are appreciated!

Yours,

Klaas van Gend
