Description Vasyl Kaigorodov 2015-06-15 14:13:44 UTC

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.
