Followup-For: Bug #276948
I compiled Xvnc using :
apt-get source vncserver
added -g in compile flags
run ./configure --with-x --with-installed-zlib
run make World in Xvnc directory
I got:
$ gdb ./Xvnc

Well. I have looked at the code now... and ... the code seem actually
to be pretty safe...
/*
* rfbLog prints a time-stamped message to the log file (stderr).
*/
void rfbLog(char *format, ...)
{
va_list args;
char buf[256];
time_t clock;
va_start(args, format);
time(clock);
strftime(buf, 255, %d/%m/%y %T , localtime(clock));
fprintf(stderr, buf);
vfprintf(stderr, format, args);
fflush(stderr);
va_end(args);
}
Can it be some 32 vs 64 bit encoding errors here?
I have no clue why it break here actually... Maybe some optimizing bug
in the x86 gcc?
