Thanks for testing such a recent snapshot.

Was that using libgmp?
What does "src/expr --bignum 1" do?
Near the bottom of tests/misc/expr, there's code to
remove the bignum-related tests if that command fails.

Here's a shot in the dark:

  Could it be that expr is a built-in for that shell?
  If so, telling Coreutils.pm's run_tests to invoke it via env
  should solve this one:

diff --git a/tests/misc/expr b/tests/misc/expr
