I too noticed this problem and spent last Saturday tracking it down.
The problem is in the new size given to the second GROWSTR in str_gets.
The previous weekend I tracked down the problem with the test script
t/op.unshift.  This was caused by aunshift not keeping the old array size 
before calling astore and having it resize the array.  Both bugs cause malloc 
arena overwrite problems.  I mailed fixes to Larry Wall, so hopefully we will
see official patches for them soon.
(Larry, you did get the mail, didn't you?  E-mail being what it is :-)
