See the bug for a reduction and the gimple trees. validate_arglist definately is rejecting the arglist in EmitBuiltinAlloca. (try: bool TreeToLLVM::EmitBuiltinAlloca(tree exp, Value *&Result) { tree arglist = TREE_OPERAND(exp, 1); if (!validate_arglist(arglist, INTEGER_TYPE, VOID_TYPE)) { debug_tree(arglist); return false; } Value *Amt = Emit(TREE_VALUE(arglist), 0); Amt =
