chicken developer Moritz Heidkamp reports:
The substring-index[-ci] procedures of the data-structures unit are
vulnerable to a buffer overrun attack when passed an integer greater
than zero as the optional START argument.
As a work-around you can switch to SRFI 13’s
string-contains procedure which also returns the substring’s index in
case it is found.
