Thanks for the suggestion.

Unfortunately when I tried the afore-mentionned snippet with `(declare (speed 0))` added after the documentation string of the `test` function, the execution results still indicate that the START variable is unexpectedly set to nil, for some reason.

I surely have no opinions against closing this bug, as it seems to be fixed on the master branch, though I have not tried yet. 

Thanks to all for all the great work, especially to Mr.Andrea for the excellent native-compilation feature.  =)
