----------------------------------------------------------------
It turns out that non-TLS (http) ports disable spdy by default. So, this core
dump is not caused by spdy over http connection. Further, the core re-appeared
in our prod hosts.
Debugging further, it seems that, due to some unknown reason, the event handler
may have dispatched the event to Spdy FetchSM, which tried to process this as a
fetch event. The MIME response header that spdy tried to submit as a syn_reply
seems like garbage (mime hdr length for the response is non-zero, but,
m_freetop seems to be zero, which doesn't make sense).
Below is some gdb output
{code}

It turns out that non-TLS (http) ports disable spdy by default. So, this core
dump is not caused by spdy over http connection. Further, the core re-appeared
in our prod hosts.
Debugging further, it seems that, due to some unknown reason, the event handler
may have dispatched the event to Spdy FetchSM, which tried to process this as a
fetch event. The MIME response header that spdy tried to submit as a syn_reply
seems like garbage (mime hdr length for the response is non-zero, but,
m_freetop seems to be zero, which doesn't make sense).
Below is some gdb output
