Previously I had a 9.3 client running on a different pc and I was able to get to May 2 2018 before I got bad allocation error. I could never get past that point on that pc. When I tried to copy the blocks, chainstate etc. to another laptop from a backup dated sept 2017, it would load then crash. I could always restart from the sept backup on the original machine and it would run to april or may before getting the allocation error. So maybe you should wait until the full reindex is done before putting the blocks, etc on github.
