[Bug tree-optimization/18519] [4.0 Regression] ICE: Segmentation fault at -O3


------- Additional Comments From pinskia at gcc dot gnu dot org  2004-11-16 14:27 -------
Confirmed reduced testcase:
struct QChar {
  unsigned short ucs;
} ;
int tibetan_form( const QChar &c );
static inline int tibetan_nextSyllableBoundary( int start, bool *invalid, QChar *uc)
{  
  int pos = 0;
  int state = tibetan_form( uc[pos] );
  if ( state != 1 )
  {
    if ( state != 0 )
      *invalid = 1;
    goto finish;
  }
finish:
    *invalid = 0;
  return start+pos;
}

void tibetan_shape( int from, int len, QChar *uc)
{
  int sstart = from;
  int end = sstart + len;
  while ( sstart < end ) {
    bool invalid;
    tibetan_nextSyllableBoundary(sstart, &invalid, uc );
  }
}


: Search converges between 2004-10-26-161001-trunk (#611) and 2004-11-03-014001-trunk 
(#612).

Really only -O1 -finline-functions is needed.
