Yeh. Memory bugs are just terrible to find.
I once had one in C code where I was mallocing space for a new string:
buf = malloc(len(string + 1));
My eyeball looked at that a jillion times before I realized that I had
a misplaced ')' and it should be:
buf = malloc(len(string) + 1);
The problem is that it crashed much later, after I wrote to the space
(and overwrote the memory), and then it finally crashed in another
call to malloc. This is typical. Between the bug and the crash were
many many instructions and many many times of writing into malloc'ed
Anyhow, Python, I kiss your feet, for taking this stuff out of my life.
