// This program used to cause G++ to dump core.  It now causes an internal
// compiler error.

// All of this, both code and options, seem to be necessary to tickle
// the bug.  Don't ask _me_ why; I don't see how they are related....

// The result of ``g++ -v -c -O -g -funroll-loops bug006.cc'' is attached below.
