You didn't say what compiler or architecture. I have code for the
Compaq Alpha F90 compiler that intercepts ALLOCATE calls and can do
things like initialize the data to NaNs. Similar things could probably
be done to, say, the PGI F90 compiler for x86, but you'll have to
figure out the interface of the library routine.

You would then need to know how to set the compiler up to crash when
it touches a NaN, but that's often not that hard.
