Can be reproduced with the following snippet:

Time.new("2020-10-28T16:48:07.000Z")

I suspect but haven't confirmed that this bug was introduced in the fix for [Bug #19296] cc @nobu (Nobuyoshi Nakada)

I have a patch for it, I'll open a PR in a couple minutes.

bignum.c: rb_int_parse_cstr handle 0 strings

[Bug #19390]

We shouldn't check the string length when skipping zeros, as the
string might only contains zero characters, resulting in an empty string.
