[GitHub] [trafficserver] sudheerv commented on issue #6849: Crash in ssl_read_from_net due to assert failure for null buffer block

   It looks like the root of the problem is that `IOBufferData::_size_index` seems garbage (3833167203381096996). This typically comes down via the call to `new_MIOBuffer` but, reviewing the code seems like the `alloc_index` passed with `new_MIOBuffer`, couldn't find a smoking gun yet where this could be garbage.
   
   Specifically, the line number (location) from the corrupted IOBufferData shows HttpSM.cc:5840 and the logic in that code block that sets alloc_index didn't seem to have any issues.
