<pre>I've succeeded to reproduce this flaky problem. The reproduction
ratio of this problem depends on which Perl is used and which version
of Cygwin is used.
64bit ActivePerl : never happen
64bit latest Cygwin Perl: never happen
32bit latest Cygwin Perl: I saw the problem only once
32bit 5-month-old Cygwin Perl: about 10%
32bit 3-year-old Cygwin Perl: never happen
I dumped $! and $?.

Sometimes different error message and no error message:

This seems Cygwin fork failure problem.
<a href="https://cygwin.com/faq/faq.html#faq.using.fixing-fork-failures">https://cygwin.com/faq/faq.html#faq.using.fixing-fork-failures</a>
I'd like to request installing ActiveState Perl on BuildBot as
described in this page <<a href="https://webkit.org/webkit-on-windows/">https://webkit.org/webkit-on-windows/</a>>.
And, Uninstall Cygwin because cmake script append a path to cygwin.
