Same error messages and results (core dumped; segmentation fault).

/var/log/messages shows the following error:
Mar  3 08:53:38 betadrive kernel: pid 21163 (bbcp), uid 0: exited on signal 11

Eventually, the following messages show on the console (usually 30 seconds
after the core dump):

bbcp: Accept timed out on port 5031
bbcp: Unable to allocate more than 0 of 4 data streams.


Tested the following configurations, all with the same results:

Send:  20150116
Recv:  20150116

Send:  20150116
Recv:  20120520



The following configuration gives difference error messages and doesn't core
dump:

Send:  20120520
Recv:  20150116

bbcp: Invalid argument unable to connect to offsite.backups.sd73.bc.ca port
5031
bbcp: Unable to allocate more than 0 of 4 data streams.

bbcp: Accept timed out on port 5031
bbcp: Unable to allocate more than 0 of 4 data streams.



The only configuration that works is:

Send:  20120520
Recv:  20120520


Command used for testing:

bbcp -N io "zfs send -I poolname/backups/folder at 2015-01-21
poolname/backups/folder at 2015-01-22" username at remotehost:"zfs recv -d poolname"


I'll make a new core file available here shortly:
