------- Additional Comments From ebotcazou at gcc dot gnu dot org  2003-09-08 06:16 -------
Confirmed on i586-redhat-linux-gnu as of 3.3.2 20030904 (prerelease) with:


void generic_sendmsg (char *fmt, ...)
{
  __builtin_next_arg(fmt);
}

void generic_sendstat()
{
  double t;

  generic_sendmsg("F %3.2f", t);
}


% gcc-3.3.2 -O3 pr12180.c
pr12180.c: In function `generic_sendstat':
pr12180.c:5: error: `va_start' used in function with fixed args


This is a regression from GCC 3.0.4.
