I've no problem with your program. Only issue I see with
MSVC-2019 in debug-mode ('-MDd -RTC1 -RTCu' in CFLAGS and using mpir.dll),
is in speed.exe. When running:
speed -c -s 10(10)1000 mpn_preinv_divrem_1f.3333
gives this call-stack:
speed!failwithmessage(void * retaddr = 0x0006e5c7, int crttype = 1, int
errnum = 4,
char * msg = 0x0053d5e8 "Stack area around _alloca memory reserved by
this function is corrupted.Address: 0x0053D780.Size: 220.Allocation number
within this function:

speed!_RTC_AllocaFailure(void * retaddr = 0x0006e5c7, struct
_RTC_ALLOCA_NODE * pn = 0x0053d760,
int num = 1)+0xd2
speed!_RTC_CheckStackVars2(void * frame = 0x0053d8e4, struct _RTC_framedesc
*,
struct _RTC_ALLOCA_NODE * allocaList = 0x0053d760)+0xa6
speed!speed_mpn_preinv_divrem_1f(struct speed_params * s = 0x001206a0)+0x407
speed!speed_measure(<function> * fun = 0x0006e1c0, struct speed_params * s

speed!run_one(struct _iobuf * fp = 0x61fd5a78, struct speed_params * s =
0x001206a0,
long prev_size = 0x1e)+0x32c
speed!run_all(struct _iobuf * fp = 0x61fd5a78)+0x188
speed!main(int argc = 5, char ** argv = 0x00747750)+0xa6a
speed!invoke_main(void)+0x33
...
Increasing the stack with 'LDFLAGS += -stack:5000000'
does not help.
