Actual output: Segmentation fault

Busybox 1.16.2, as downloaded from busybox.net, and self-compiled. Running
under the built-in ash shell. Current environment: kernel 2.6.34, glibc 2.11.2,
gcc 4.5.0.

Other info: I have seen this come and go over the 1.16.x series -- with and
without the various patches applied, and with slightly older versions of kernel
/ glibc / gcc.
