+### INABIAF - it's not a bug it's a feature! :-)

+If you use either `fubar` or `ouroboros.c` (it's executable, see below) with a
+number < 0 or larger than, say 20, it's very likely that the program will turn
+into an infinite loop trying to compile code with syntax errors.
 
 ## Judges' remarks:
 
-Run this with a single digit argument (or wait a long time).

 The blank line at the beginning of the source is mandatory.
 Do you know why?
 
-NOTE: don't try running `ouroboros.c` (note that it's executable)
-directly with an arg as it'll turn into an infinite loop. The same will happen
-with larger numbers.
-
 NOTE: the file `ouroboros.c` is created by the program itself so this is why it
 is not in the repository.

+## STATUS: INABIAF - please **DO NOT** fix
+
+Specifying too large a number (or < 0) to either `fubar` or the source code file
+(it's executable) that it generates will cause the program to enter an infinite
+loop, trying to compile code with syntax errors. At least in one system any
+number larger than 20 did this.
