An Internal compiler error has been reported on the macpascal mailing list, as reproduced by the following program: [G5:gcc/p/test] adriaan% cat avo10.pas program avo10; type UInt16 = cardinal attribute( size = 16); StyleItemGPC = (bold,italic,underline,outline,shadow,condense,extend); StyleParameter = UInt16; procedure TextFace(face: StyleParameter); external name 'TextFace'; begin TextFace( [bold, italic]); {internal compiler error} end. [G5:gcc/p/test] adriaan% gpc avo10.pas ../../gcc-3.4.3/gcc/p/typecheck.c:123:incomplete_type_error: failed assertion `0' avo10.pas: In main program: avo10.pas:8: error: Internal compiler error.
