mysterious segfault with busybox 1.13.0 ash

[Natanael Copa]

Hi,

I have not been able to reproduce it in a small test script but it
happens exactly here:
http://dev.alpinelinux.org/cgit/cgit.cgi/alpine-baselayout/tree/init.d/runtimes#n178

row 178.

I suspect it is related to the ! operator. If I insert:

! false && echo foo

the script will segfault and no "foo" will be echoed.

If i insert:

false || echo foo

the "foo" will be echoed and ash segfaults, at the "if ! tar ..."

Unfortunally, I'm not able to reproduce in a smaller script.

ideas on how to narrow it down?
