fix following warning by dynamically allocating memory: dgnc_tty.c:583:1: warning: the frame size of 1060 bytes is larger than 1024 bytes [-Wframe-larger-than=]
Signed-off-by: Martin Kepplinger <martink@posteo.de> --- This is more of a question. Is this a desired solution to fixing such a frame size warning?
thanks, martin
