There is now a workaround in system_with_timeout() to avoid issues with quotes and spaces in the filenames of the executable by using start[1]. However, calling start will not propagate the process status of the actual process. Thus, calling proc_get_status() is pretty meaningless, and especially Microsoft errors cannot be detected (typically, access violations etc.), and as such no "Termsig" message is output.

We fix this by executing exit after the started command has finished.

	// when proc_open cmd is passed as a string (without bypass_shell=true option) the cmd goes thru shell
	// and on Windows quotes are discarded, this is a fix to honor the quotes and allow values containing
	// spaces like '"C:\Program Files\PHP\php.exe"' to be passed as 1 argument correctly

	$commandline = 'start "" /b /wait ' . $commandline;

Given the proc_open() escaping fixes that have been done in the meantime, it may also be possible to drop the start workaround on Windows altogether; a quick test worked as expected, but I haven't done extensive testing.

Sorry to bother you, @nielsdos, but you've written that code, and I think fixing the issue (namely that segfaults in tests may go unnoticed on Windows) is pretty important. I'm not sure if the & exit hack is preferable, or whether we should drop the whole start /b /wait wrapping.

Seems fine, wasn't aware tbh that this would interfere with the access violations on Windows.
proc_open seems to be the better option but we can delay that.
