[CsMain] Cygwin crash (ptmalloc?)

[Michael D. A. <mdm...@gm...>]

I'm getting a crash on exit in walktest that I wasn't getting
yesterday, so I'm guessing it was the ptmalloc merge.  Res, are there
any obvious places I should look in ptmalloc?

(Last time Cygwin had a crash on exit it was due to a static variable
inside a function.  For some reason Cygwin doesn't like those.  The
fix was to move the static variable to outside the function.  It
doesn't look like ptmalloc has any of these.)
