It seems that if compilation is not required, or if compilation is very
fast, ghc -Rghc-timing will throw up a Floating point exception:
[hdaume@hal3 timing]$ ls
Timing.hs
[hdaume@hal3 timing]$ cat Timing.hs
module Timing where
timing = undefined
[hdaume@hal3 timing]$ ghc -Rghc-timing Timing.hs -c
<<ghc: 9358352 bytes, Floating point exception
[hdaume@hal3 timing]$ ls
Timing.hi Timing.hs Timing.o
[hdaume@hal3 timing]$ rm *.hi *.o
[hdaume@hal3 timing]$ ghc Timing.hs -c
[hdaume@hal3 timing]$ ls
Timing.hi Timing.hs Timing.o
[hdaume@hal3 timing]$
Am I right or is something else going on here...?
