This is a resurgence of issue #356, which is closed and locked (why?).

Using Nucleo L073RZ.
It does not happen with any other chips I tried.

ST_link firmware is V2J29M18, st-flash version 1.4

Mass erase, as suggested in the README is slow, goes through fine, but doesn't resolve anything.

The flashing is extremely slow, but despite the errors shown, after a board reset with the hardware button the uploaded firmware seems to be working correctly.

Ah, I see there's a couple old issues with this exact error, c 8000 losed as "will be fixed in 1.2" or so - alas...
