Hej Sslugere
Jeg arbejder på en threaded qt-application (jeg har egenligt ikke brug
for thread'ene, men jeg kan ikke lave openGL uden).
Applikationen kører fint hvis den bare startes fra prompten.
Men hvis jeg starter den fra gdb får jeg følgende:
(gdb) r
Starting program: /home/ribe/code/umbrella/umbrella
Program terminated with signal SIGSEGV, Segmentation fault.
The program no longer exists.
Når jeg så kigger i sysloggen står der følgende:

Kernen er en 2.6.8.1-mm4 og gdb er 6.1-Debian.
Ved opstart skriver gdb:
