Question: on the VAX, where there is subscript checking hardware,
which compilers use it?
Incidentally, I once built the Berkley C/Pascal code generator for
the VAX with the entry mask generation set to enable integer underflow
and overflow checking. Almost none of the stock Unix programs will work
with it enabled. This is partly because the compiler isn't careful about
generation of shift instructions, and shifting into the sign bit is illegal.
