Well, there has been (is?) a problem with interrupts on the ARM using 
GCC.  There should be others lurking here with more information on that. 
BTW, I just checked I'm using 3.3.2 and it's not that new.  If you are just 
starting I'd really seriously consider a newer version.

I don't trust compilers for this sort of thing anyway.  More fodder for my 
paranoia :)
