Leif Hedstrom commented on TS-2654:
-----------------------------------
Since I removed the additional call to
change_response_header_because_of_range_request, this must be a different crash
that what we initially thought. This is using the latest master ?
If someone could produce a useful stack trace, which has information about
where and why it's actually causing this crash, maybe we can debug it. But,
assuming you are using the latest master, the crash can not be related to the
changes I made, because I reverted the call to
change_response_header_because_of_range_request().
> Range request crash in trafficserver 4.2.0
