Unfortunately, that's not enough. One practical issue is the MS-Windows
environment (again) and the Microsoft runtime. We have the following in
MPFR's INSTALL file (note the mention of GMP):

Yes, but note that this is also the case with GMP, for the
formatted output functions. :)
Yikes! I wasn't aware of that

Perhaps it could be nice for GMP to also have mpz_set_sj and
mpz_set_uj in addition to mpz_set_si and mpz_set_ui.
I have a probably incomplete patch

Possible explanation:
mpz_set_si function has the signature:
void mpz_set_si (mpz_ptr dest, signed long int val);
Indeed. And you pass an int64_t which may or may not be "signed long
int". That's a bug in your program,
Hello,
I'd like to report a problem with mpz_set_si on Windows 64 (Mingw)
GMP version: 6.1.2
Platform: minw32 on linux ubuntu 18
the program to check:
test-mpz.cpp:
#include
#include
#include
int main() {
mpz_t mpz_a; int64_t a;
int64_t b = 710;
