You didn't show us the contents of

Your /bin/sh is buggy.  POSIX says that implementations should tolerate
(that is, silently ignore or erase) invalid environment variable names
that they do not understand, rather than loudly complain.  Since Mac OS
is proprietary, I cannot help you fix your /bin/sh; but please raise a
bug report to Apple to fix their /bin/sh.
