Thanks for the data, unfortunately I still have no clue.  The fact that
both dash and bash fail looks like it could be a libc or kernel issue.

Can you post (gzip'ed) trace of
  strace -f -o trace make check SHELL='/bin/bash -x' TESTS=bug23

and maybe make the package available so we can try it out?

Thanks,
