Do not delegate the secondary stack management when there is no suitable transient context, and the transient scope was intended to manage the secondary stack because this causes premature reclamation. Change the transient scope creation logic by special casing assignment statements of controlled components for type initialization procedures. (Find_Node_To_Be_Wrapped): Renamed to Find_Transient_Context. Update the comment on usage. (Find_Transient_Context): Change the initinte loop into a while loop. Iterations schemes and iterator specifications are not valid transient contexts because they rely on special processing. Assignment statements are now treated as a normal transient context, special cases are handled by the caller. Add special processing for pragma Check. (Is_OK_Construct): Removed. Its functionality has been merged in routine Find_Transient_Context. * sem_ch5.adb (Check_Call): Reimplemented. Add code to properly retrieve the subprogram being invoked.
