Thanks for your report. I'm now debugging. Use -O0 if you want to complie it
for the present.

The smaller code to reproduce this bug:

/usr/tools/lib/gcc-lib/shle--netbsdelf/2.95.3/cc1 -O  -W -fno-argument-alias -fno-defer-pop -fno-thread-jumps -fno-peephole -fno-function-cse -fno-inline -fno-keep-static-consts -fno-reg-struct-return -fno-pcc-struct-return -fno-delayed-branch -fno-sjlj-exceptions -fno-ident -Wall -Wstrict-prototypes -Wmissing-prototypes -Wpointer-arith -Wno-uninitialized  -Werror  -nostdinc -isystem /usr/include  tst.i

---- tst.i ----
void	 f  (char **);

static char *
compile_flags(p)
     char *p;
{
  char wfile[128];

  for (;;) {
    switch (*p) {
    case ';':
      return (p);
    case '7':
      f(&p);
      break;
    }
  }
}
