What is exactly the base pointer and stack pointer? To what do they point?
...register and access locals directly off of esp, but this makes debugging a bit more difficult since the debugger can no longer directly access the stack frames of earlier function calls.
EDIT:
For your updated question, the missing two entries in the stack are:

... If you're dealing with DNA strings only: You can compress a char into two bits and pack your data quite a lot. This will cut down the memory requirement by factor four over a naiive representation. Addressing becomes more complex, but the ALU of your CPU has lots of time to spend during all the cac...
How do I trim leading/trailing whitespace in a standard way?
...ecause char index values must be cast to unsigned char. The code assumes 8-bit char. delim should be declared as const char *. dtab[0xFF & (unsigned int)*d] would clearer as dtab[(unsigned char)*d]. The code works on UTF-8 encoded strings, but will not strip non ASCII spacing sequences.

Indeed, if we ask the compiler to try just a little bit harder to inline that function, the difference in performance goes away.
So what is the take away from this story? That failed inlines can cost you a lot and you should make full use of the compiler capabilities: I can...
How many random elements before MD5 produces collisions?
...housand 456.
However if you keep all the hashes then the probability is a bit higher thanks to birthday paradox. To have a 50% chance of any hash colliding with any other hash you need 264 hashes. This means that to get a collision, on average, you'll need to hash 6 billion files per second for 100...
