My guess here is that it’s, as usual, the fault of qemu-user,
Strong evidence for that: doesn’t look like it even executes
one bit of klibc code:
$ qemu-arm-static -d cpu ./fstype --help
qemu: uncaught target signal 11 (Segmentation fault) - core dumped
Segmentation fault (core dumped)
what does this show?:
QEMU_STRACE=1 qemu-arm-static -d cpu ./fstype --help
I still believe, that the problem is that qemu's brk(NULL) doesn't return
a page-aligned address, which will have lots of other side-effects.
