I cannot reproduce this with today's code, though did make a fix to a
potentially related region of code.  For segv reports, it is helpful
to run the program under a debugger to produce a stack traceback at
the moment of crash.  Please consider using bugzilla.

I don't see this problem either.  Maybe your source checkout was
botched.  A parse error in unistd.h is of course very strange.
