+
+ * exp_ch5.adb (Expand_Formal_Container_Element_Loop): Remove the code
+ to analyze the Elmt_Decl, because it gets analyzed in the wrong scope.
+ We need to analyze it as part of analyzing the block, so that if the
+ call to Element that initializes Elmt_Decl returns on the secondary
+ stack, the block will ss_mark/ss_release. This block is inside the
+ loop; we don't want to leak memory until the loop exits. The purpose
+ of analyzing Elmt_Decl first was to catch the error of modifying it,
+ which is illegal because it's a loop parameter. The above causes us to
+ miss that error. Therefore, we add a flag Is_Loop_Parameter, and set
+ it on the Element entity, so we end up with an E_Variable node with the
+ flag set.
