Using gcc's Address Sanitizer, it was discovered that the
string-translate* procedure from the data-structures unit can scan
beyond the input string's length up to the length of the source
strings in the map that's passed to string-translate*. This issue was
fixed in master 8a46020, and it will make its way into CHICKEN 4.10.

This bug is present in all released versions of CHICKEN."
