oops. For powerpc32 plain 'long' doesn't map to one of the store-able types.
'pvd::int32' is an alias for 'int' and 'pvd::int64' is 'long long'.
(It's a pity that c++ doesn't have a portable way to make this error clearer)
Casting to double should do the trick. (or pvd::int32 or pvd::int64)

I agree. The question is where.
