chicken developer Peter Bex reports:

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.
