[Rasca Gmelch <thron gmx de>]

hi,

if i compile my program without the -O flag the program receives
a seg. fault on startup. i use the egcs 2.91.66 with linux
kernel 2.2.11 and gtk+ 1.2.3. any ideas? the gdb trace is below:

(gdb) run
Starting program: /opt/home/rasca/studium/Diplom/diplom/pano/xcam/xcam
