Indeed. I simplified my example to make it shorter. On unix systems I use
nouse_stdio to avoid this problem (that doesn't work on Windows though,
but that's a different issue).

Redirecting to a file is the workaround I'm using, but I was hoping someone
would know what the problem is and whether it can be fixed. :-)
