[SDL] Fatal signal: Segmentation Fault (SDL Parachute Deployed)

[benang at cs.its.ac.id]

Well, I've tried running it from gdb and it worked fine. All attempts to
recreate the problem is not working. And when I used valgrind, it didn't
work. It exited the valgrind even at the start of the program. When I
looked at the backtrace of valgrind, it returned lots of error like:

Use of uninitialised value of size 4
.....

Invalid read of size 4
.....

Syscall param ioctl(arg) contains uninitialised byte(s)
.....

Syscall param write(buf) points to uninitialised byte(s)
.....

Segmentation fault


The funny thing is, even when it cannot be run from valgrind, I can run it
from the terminal console (until the SDL Parachute deployed).
