Fred, OK I just noticed I didn't have the -malign-double flag. With that it compiles but on running I get:
Program received signal SIGSEGV: Segmentation fault - invalid memory reference. Backtrace for this error: #0 0x12244B #1 0x122A9C #2 0x473907 #3 0x1BD238 #4 0x1CB4BF #5 0x80486E2 in MAIN__ Segmentation fault Without that flag it compiles & runs without error. So you may want to try it just without that flag.
