Fehler reproduzierbar?

[403]

nein, leider nicht.

EDIT: Ich seh grad, das gehoert eigentlich nach Andere Betriebssysteme. Sorry.

Kein Ding, der kann hier bleiben. Wenn es sich nicht reproduzieren lässt, ist es natürlich problematisch. Hattest du das Problem häufiger, spontan, oder war es das erste Mal?

[403]

nein das war das erste mal. hier noch die compile flags:
