seen with the gcc-13 branch building openssh, removing either the
-fzero-call-used-regs=used or -fPIE avoids the issue.

I can't reproduce this with the trunk.

$ cat moduli.i
int snprintf_eta;
double snprintf_time_per_line;
int snprintf(char *, int, char *, ...) {
  snprintf_eta = snprintf_time_per_line;
}

$ m68k-linux-gnu-gcc -c -O2 -fno-strict-aliasing -fzero-call-used-regs=used
-fPIE moduli.i 
during RTL pass: zero_call_used_regs
moduli.i: In function ‘snprintf’:
moduli.i:5:1: internal compiler error: in change_address_1, at emit-rtl.cc:2287
