As a temporary workaround, tzdb 2018e should work fine for Brazil 
(though 2018e is missing some updates for other locations that you 
probably don't care about).

The underlying problem is that the Oracle tool doesn't grok timestamps 
like "25:00" in zic input files. We're looking into ways of fixing this 
in a better way for the next release.
