If you pass an uninitialized pointer to a library routine, it's likely
to segfault. This is *your* bug, not the library's, because the library
routine has no way to know that you gave it a random pointer value
instead of something that actually points to valid data.
You might want to adjust your compiler switches so that the compiler
warns about uses of uninitialized variables. In gcc, "-O -Wall" is
a pretty good combination.
