compile with -O3 or higher, and execution generates seg-fault

The included file compiles with just -O3 or higher as arguments.  It should run
and print a bunch of lines to stdout, then exit normally.  When compiled at -O3
or higher, it generates a bus-error on the command line, due to a segmentation
violation signal when run from the debugger.
