I applyed your patch and add my additional debug string.
Now result is:

Seems this issue is solved.
Can you apply this patch to 5.0 branch?
Then may be Pete Kelly will install nightly build of the 5.0.1 and
confirm that issu is solved.
I does not have such count of sbc for test )
Thank you Daniel.
