A static analyser for C & C++ called cppcheck. Available from sourceforge.

I think you can also get a similar warning if you tweek the gcc compiler warning
flags. -Wformat=2 maybe.

I don't know the code, but given that insn is unsigned long and so can go
past 32 bits, using a cast to unsigned int might throw away the
possibly important
upper bits.
