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.
