I don't like the '-inline' option, but here it is.  Besides, I usually
use GDC or LDC2 and I was expecting them to outperform DMD because
they usually do, but not in this case.


DMD-32bit  v2.52 -O -release -inline
[VIRT: 94MB,  RES: 92MB]
real    0m42.490s
user    0m42.480s
sys     0m0.000s

DMD-32bit  v2.53  -O -release -inline
[VIRT: 107MB, RES: 104MB]
real    0m34.011s
user    0m33.930s
sys     0m0.070s

DMD-64bit  v2.53 -O -release -inline
segmentation fault

DMD-64bit  v2.53 -O -release
[VIRT: 232MB, RES: 219MB]
real    0m44.715s
user    0m44.580s
sys     0m0.080s

P.S.
It's a 64-bit system.
