Summary:                    ash crashes on mpc8349 powerpc platform - free
invalid pointer
Description: 
I used to post a message on mailing list, and now I think it should be a
bug.

Recently I'm playing embedded system running on mpc8349 (powerpc).
I built the toolchain myself, including glibc-2.4, binutils-2.17 and
gcc-4.1.1
Then I downloaded the busybox 1.4.1 and built it.

I traced into ash.c and found that, when running evalcommand(), in the
function evalbltin(), the mark->stackp will be cleared to NULL after
calling

if ((i = setjmp(jmploc.loc)))

But I have no idea about what's setjmp() doing.

Was discussed on ml and found to be a setjmp/longjmp miscompilation.
Old/broken toolchain?
