BusyBox 1.2.1 piping issue

[Coleman Brumley]

Hello.

I'm having an issue with BusyBox v1.21 and piping.  It seems as though 
piping is causing busybox to restart/crash.

For example:
/# echo abcd | grep a


BusyBox v1.2.1 (2007.03.26-18:36+0000) Built-in shell (ash)
Enter 'help' for a list of built-in commands./

Has anyone run into this or anything similar?

TIA,
Coleman
