// { dg-do assemble }
// { dg-options "-O -Wall -fgcse -frerun-loop-opt" }

// Reported against EGCS snaps 98/06/28.

// Compilation of this program with the flags g++ -Wall -O -fgcse
// -frerun-loop-opt or -O2 produces spurious warnings in the standard
// header <std/bastring.h>.
//
// They vanish if the declaration of a::b is taken out.
