Fixed in r32229. The problem is that retrieving the STRING value of a String Key returned that STRING directly. Modifying its contents modifies the STRING in place -- and freeing that STRING frees its contents.

I changed key_string() to return a COW string in this circumstance instead. That means anyone can modify the received STRING without modifying its parent. I also added your code as a test case in t/pmc/key.t. -- c
