hex string has incorrect length & stuck at switch forks at block

[aping]

I built the master branch (commit 381b1cc) to work with eos 2.1.0 and found two problems:

1. When I stop fill-pg process and start again, it reports hex string has incorrect length.
   Looks like the error comes from https://github.com/EOSIO/history-tools/blob/master/src/state_history_pg.hpp#L43
   I built with eosio_2.1.0-1-ubuntu-18.04_amd64.deb and eosio.cdt_1.8.0-1-ubuntu-18.04_amd64.deb, boost version is 1.76.0
   not sure if it matters.
2. fill-pg process stuck at switch forks at block xxx (process not responding, has to kill -9).
   gdb backtrace shows:
