This works OK under 2.6.4-1.305, but does not work under 2.6.4-1.303 (or at least in SELinux enforcing mode). Weird... I can not reroduce it under kernel 2.6.4-1.305, and under 2.6.4-1.303 (where I saw it) a lot of weird things were happening. Should this be considered a kernel-related bug that was already fixed and be closed, or are you interested in trying to investigate it further? I'm going to guess "bogon kernel" -- if it happens in something newer, could you reopen? I got similar bug running nash(initrd) in User Mode Linux environment.
mkinitrd-3.5.19
I used Linux + uml patch - v2.6.6. My general kernel is FC2 derived
(kernel 2.6.3-2.1.253)
I found such dependencies. If I compile nash against dynamic libc
library it works without segfault. It crashes when it is linked
statically against dietlibc library.
FYI
