gcc.c-torture/execute/980223.c aborts with -O -p on alpha-osf4

["Kaveh R. Ghazi" <ghazi at caip dot rutgers dot edu>]

	When I compile gcc.c-torture/execute/980223.c with -O -p
(really any opt level) on alphaev5-dec-osf4.0b the resulting
executable gets an abort.

	This does not occur if I use -pg instead of -p.

Here's the gcc -E output from 980223.c:
