This looks very suspicious to me.  You are trying to pass *two*
arguments on the #! line.  If that worked it would be quite
unportable.  Different kernels deal with that differently.  I would
fully expect that both of those second arguments would be treated as
one, that is, no argument splitting.  But it will actually work on
some systems.

Run it with strace.  Is it exec'ing itself repeatedly?

  $ strace ./env-test.sh
