Well I haven't used compiled code explicitly much, but as I understand 
it, the results should be the same as non-compiled code, except perhaps 
for rounding errors.

Therefore, if I had code that worked in interpreted mode, but not in 
compiled mode, I would try to thin the code down to the smallest 
fragment that showed a problem, and then perhaps report it as a bug to 
Wolfram.

I would also test code before trying to compile it - so if you are 
talking about bugs that are there anyway, get them out before you use 
the compiler! To do this, you may need to scale the problem down a bit 
so that it can execute without the compiler in a reasonable amount of 
time. Usually this is fairly easy.
