Description
Tim Newsha reports: When H2O tries to disconnect a premature HTTP/2 connection, it calls free(3) to release memory allocated for the connection and immediately after then touches the memory. No malloc-related operation is performed by the same thread between the time it calls free and the time the memory is touched. Fixed by Frederik Deweerdt.
