Oh. It is my error. I used "buildCall1 (s, cVoid, cPointer)", but I must use "buildCall0 (s, (), cPointer)" Sorry. Thank you very much.

Hi, The assertion failure is in libffi so I'm not sure what is going on there. It's possible that Poly is doing something wrong but assertion failures are usually faults in the code itself.

The "Address out of bounds" message is simply something from the debugger. The value is a union which may sometimes be an integer and sometimes an address. In this case it is a small integer and isn't valid as an address.

Hello. I got FFI error when configure and built poly with --enable-debug *only*: ASSERTION FAILURE: 0 at src/x86/ffi64.c:302

The error happens on Linux and FreeBSD. I use PolyML from git at "Thu Jan 3 14:35:50" date (Linux) and "Fri Jun 22 13:49:32 2018" (FreeBSD): ./configure --with-gmp --enable-debug

When I use PolyML *without* debugIt is all right. :-)

GDB backtrace on linux:

GDB backtrace on FreeBSD is more informative ans say "0x6f <Address 0x6f out of bounds>":
