I managed to reproduce this. Cygwin's compiler hard-codes the constant 0.1
with not enough precision for what ECL attempts to do. As a result,
scale-float in ECL's src/lsp/format.lsp ends in an infinite loop. I am
uploading a patch that seems to solve the problem. I could not test the
other thing yet.
