If you turn off if-conversion it will compile. See http://gcc.gnu.org/ml/gcc/2004-02/msg01115.html for some analysis from Jim Wilson. This was tested with the ToT sources dated 20040212 and also exists on older GCC compilers for IA64 Linux. typedef union YYSTYPE { double dval; int intval; } YYSTYPE; YYSTYPE *x; int knparse (void) { YYSTYPE yyvsa[200]; register YYSTYPE *yyvsp; YYSTYPE yyval, *x; yyvsp = &yyvsa[100]; if (yyvsp[3].intval > yyvsp[0].intval) yyval.intval = yyvsp[3].intval; else yyval.intval = yyvsp[0].intval; *x = yyval; } -- Summary: Compilation failure due to if-conversion Product: gcc Version: 3.5.0 Status: UNCONFIRMED Severity: normal Priority: P2 Component: c AssignedTo: unassigned at gcc dot gnu dot org ReportedBy: sje at cup dot hp dot com CC: gcc-bugs at gcc dot gnu dot org http://gcc.gnu.org/bugzilla/show_bug.cgi?id=14261
