If it can be reproduced on anyones machine, it is a bug. If you can
bundle up two programs which don't read from stdin (i.e. no getLine
calls) or the standard arguments (i.e. getArgs) which differ only by
the Data.Char import, and have massive speed difiference, then report
a bug.

You should probably also give your GHC versions and platforms etc.
