Hello,

These errors are from an AV. Many AVs try to block "stack pivots"
which interferes with Cygwin's implementation of fork(2). AV vendors
are becoming rather brazen and their products rather annoying; I've
had to threaten to just keep reinstalling the OS on work machines to
get rid of the AV.

But also once IT added a policy that should have allowed X11 it was
still not working. AVs can silently kill things with no warning, but I
am not sure if that is it or if Cygwin's X11 is broken.

I had to use Xming with DISPLAY=localhost:0.0. In restrospect Xming is
likely the reason Cygwin's DISPLAY defaults to "ocalhost:0.0."

Cheers,
