Perhaps someone here can help...

I'm doing a presentation on techniques for embedded, especially removing 
and keeping out bugs ;-) Using an example project from last year. A 
reviewer of my first draft suggested many of the bugs surfaced in the 
project would have been caught by static analysis - but I haven't had 
such great luck in the past.

Tried CPPcheck, and while it found some less-than-optimal stuff it only 
found one of the real bugs discussed.

Tried to get an evaluation copy of Coverity, but got a wildly annoying 
and clueless sales person who promises a member of the right team will 
contact me shortly (Real Soon Now).

Bugs I had to fix and amenable to static analysis included:
- uninitialized variable (only one found by CPPcheck)
- use of magic 0xff index value as subscript off end of array
- C macro with unguarded arguments getting wrong answer
- use of int8 to index 1kb buffer (so only 256 bytes got used)

Anybody able to recommend a tool they've used successfully?
Thanks in advance,
Best Regards, Dave
