Further digging shows some weirdness. This doesn't appear to be
compiler-related. I've rolled back all the way to gcc 3.5. It is
triggered by the following line in pg_regress.c, commenting out of which
causes the problem to go away (although of course it causes the
regression tests to fail):
putenv(new_pgoptions);
Oh really ... are we using src/port/unsetenv.c on that platform?
I wonder if that little hack is incompatible with latest mingw
libraries ...
It is using pgwin32_putenv() and pgwin32_unsetenv(). It appears not to
be related to how the environment is set at all, but to how the backend
is handling PGOPTIONS.
Here's a TCP level dump of traffic showing the problem. The client is on
Linux.
