Bug 13100 – std.process.setCLOEXEC() throws on invalid file descriptor

This is based on a report I received by e-mail from a D user. If a program that calls spawnProcess() is run in an environment where one or more of the standard streams are closed, the setCLOEXEC() function will throw an exception and the child process will terminate. I will send a pull request that fixes this shortly.

We just want to ignore the error in the former case, as evidenced by the bug report, and the latter means that we have an error in std.process, which is best handled by an assertion. (Note that it was never possible to catch the exception anyway, since it was thrown in the child process.) https://github.com/D-Programming-Language/phobos/commit/357b627d2b7349c5fae8fc336f988242cd9fd51f Merge pull request #2326 from kyllingstad/no-setcloexec-fail Fix issue #13100 - std.process.setCLOEXEC() throws on invalid file descriptor
