Reduced testcase:
typedef unsigned long bngdigit;
typedef bngdigit * bng;
typedef unsigned int bngcarry;
typedef unsigned long bngsize;

bngdigit bng_ia32_mult_sub_digit
 (bng a , bngsize alen,
  bng b , bngsize blen,
  bngdigit d)
{
  bngdigit out, tmp;
  bngcarry carry;
bngdigit a11;

  alen -= blen;
  out = 0;
asm(""
: "+r" (a), "+r" (b), "+mr" (blen), "+mr" (out), "=&r" (tmp)
: "mr" (d)
: "eax", "edx");
  if (alen == 0) {a11 =out; goto t;}

  a11 = 1;
  t:
return a11;
}

We are just running out of registers which is what x86 is known for.

I can't build the Objective Caml compiler with this gcc error :/
