Thanks for the detailed bug report.
It seems strange, because that line is at va_start(). I see nothing obviously
wrong there (the open() call includes the mode as it should when using
O_CREAT), so I'll install that platform and try to reproduce it.
I test libfiu on DragonFlyBSD every once in a while and I've never hit
anything like this, but since it's a related platform I'll also give it a try,
just in case.
Thanks again,
Alberto
