--- Comment #3 from Steve Ellcey <sje at gcc dot gnu.org> ---
That fixed the small testcase I created, I will try a complete build next.


For the record the test case that fails with MIPS GCC (-O2 -g -mips64) is:

_vdiprintf_r(struct _reent *ptr , int fd , const char *format ,
__builtin_va_list ap)
{
  char *p;
  char buf[512];
  int n = 512;
  p = _vasniprintf_r (ptr, buf, &n, format, ap);
  if (p != buf)
    _free_r (ptr, p);
}
