Leif Hedstrom commented on TS-2731:
-----------------------------------
I cloned this from TS-2654, since we removed the extra call to
change_response_header_because_of_range_request from master and v4.2.0, this
must be a different crash. Unfortunately, there are not enough details to debug
upon this. If someone who actually sees this crash, using latest master or
v4.2.1, please add information about the crash that we can debug on.
