gcc14 static linking ends with segfault

In replacing an ancient system with new I re-installed all ports
including lang/gcc14 of FreeBSD-current.  -current is 2 day old
sources.

Consider,

#include <stdio.h>
#include <stdlib.h>
#include "mpfr.h"

int
main(void)
{
   mpfr_t pi;
   mpfr_inits2(512, pi, NULL);
   mpfr_const_pi(pi, MPFR_RNDN);
   mpfr_printf("pi = %25.20Rf\n", pi);
// A conscientious programmer cleans up after themself,
// but on exit the system should take care of memory.
//   mpfr_clears(pi, NULL);
   return (0);
}

% gcc14 -o z -O2 -I/usr/local/include a.c -L/usr/local/lib -lmpfr -lgmp
% ./z
 pi =    3.14159265358979323846

All seems to work with shared linking.

The following used to work.

% gcc14 -o z -O2 -I/usr/local/include a.c -L/usr/local/lib -lmpfr -lgmp \ 
        -static
% ./z
pi =    3.14159265358979323846
Segmentation fault (core dumped)

% gdb151 ./z z.core

So, did someone break the startup files?
