When compiling the test in comment #43 with -O2, the size of the a.out file is

[macbook] f90/bug% ll a.out
-rwxr-xr-x 1 dominiq staff 17752 Oct  9 17:55 a.out*

with -Os it is

[macbook] f90/bug% ll a.out
-rwxr-xr-x 1 dominiq staff 30216 Oct  9 17:54 a.out*

Are these numbers misleading, or once again compiling for size does not give
the smallest size?
