hammer crash when running fsstress on an -o nohistory'd file system

:Hi,
:
:HAMMER crashes reliably when running fsstress on a file system that is 
:mounted -o nohistory.

:Crash dump is in ~swildner/crash/crash27.tbz on leaf.

    Ok, I'll try to reproduce it.  If you could generate another core
    the one you got unfortunately doesn't seem to have the backtrace
    of the actual panic on it.  I'm not sure why.

    It is possible that the assertion itself is incorrect but I need
    to track down the actual record state to figure out if that is so.
    Under fsstress conditions HAMMER is sometimes unable to fully flush
    a file in  single flush cycle which could potentially be the cause
    of the mismatched flush groups between inode and record.
