+=head1 BUGS |
+ |
+In OpenSSL versions before 1.0.0 the BIO_pop() call was handled incorrectly, |
+the I/O BIO reference count was incorrectly incremented (instead of |
+decremented) and dissociated with the SSL BIO even if the SSL BIO was not |
+explicitly being popped (e.g. a pop higher up the chain). Applications which |
+included workarounds for this bug (e.g. freeing BIOs more than once) should |
+be modified to handle this fix or they may free up an already freed BIO. |
