Hi,

I found that running a debian arm5 bash with qemu runs into varying
problems with -R but works without. Also works fine on both armv5 and
armv7hf hardware.


This happened with both master and 1.0 builds:

curl www.zq1.de/~bernhard/temp/debian-bash-bug-nss-minimal.tar.gz |\
  tar xz
cd debian-bash-bug-nss-minimal
path/to/qemu/arm-linux-user/qemu-arm -R 500M -L . bin/bash
qemu: uncaught target signal 11 (Segmentation fault) - core dumped
Segmentation fault


with chroot and our openSUSE qemu-arm-binfmt (which only does some
argv[0] magic) I saw it working after rm lib/libnss*

but otherwise it failed with messages like
bash: xmalloc: ../bash/variables.c:1971: cannot allocate 2 bytes (8192
bytes allocated)


Ciao
Bernhard M.
