Thanks. I've fixed this in git.

I reproduce that bug and step 7) and 8) can be replaced with a single re-evaluate for me. It seems to indicate very clearly that the problem is in the floating point start-up somehow and has nothing to do with `pi' or variable references. Another possibility would be that multiplication (*) was at fault, but my new smallest test-case rules that out: #lang racket .1 => 0.0 And actually it works also directly in the REPL without running any program: Welcome to DrRacket, version 5.2.0.7--2011-12-15(-/f) [3m]. Language: racket; memory limit: 128 MB. > .1 0.0 > 1 1 > .1 0.0 > .2 0.0 > .3 0.0 > .4 0.0 > .5 0.0 > .6 0.0 > .7 0.0 > .8 0.0 > .9 0.0 > 1.0 1.0 > .1 0.1 So should we look at the byte-code produced for this (how does one do that and what is the expected code)? Is there some way to invoke racket from the command line in such a way that it behaves like the drracket initial repl? How does one run the byte-code? What external suspects are there? I suppose gcc, but are there any other? My CFLAGS are set to a very conservative AFAIK CFLAGS="-march=native -ggdb -O2 -pipe", currently on version 4.5.3.
