Package: vncserver Version: 3.3.7-7 Followup-For: Bug #276948 I spend some time with a friend to find the problem.
In the default configuration, -Wall is not used for compilation. When I add it, I have warnings about implicit declaration of time, strftime and localtime Implicit declaration means the function return int (it is not as localtime return a pointer struct tm *). BUT! On amd64, we have sizeof(int) = 4 and sizeof(void *) = 8. So we loose the upper 32 bits of the result, filled with uninitialized data instead. I added '#include <time.h>' in Xvnc/programs/Xserver/hw/vnc/init.c, killed the boss monster and finished the first stage of having a working Xvnc : (gdb) run :2 Starting program:
