@ -21,3 +21,10 @@ Sandboxed main observations:
=> loop in pffft_transform for N = 64 (why?); => loop in pffft_transform for N = 64 (why?);
N = 64, status OK, pffft_transform generates error N = 64, status OK, pffft_transform generates error
N > 64, status not OK N > 64, status not OK
Problem on initialising sapi::StatusOr<PFFFT_Setup *> s;
the memory that stays for s is not the same with the address passed
in pffft_transform function.
(sapi::v::GenericPtr to be changed?)
Temporary solution (not done): change the generated files to accept
uintptr_t instead of PFFFT_Setup
