[mkgmap-dev] New assertion, now with code-page=632 and Japan tile

Wed Nov 10 08:43:49 GMT 2021

Hi Carlos,

I'll try to debug this.

BTW: I see you use *.o5m for the tiles (output from splitter). I think this is no longer a good choice, pbf is a lot smaller and almost as fast. Esp. when it comes to the goal of reducing disk I/O (as with --gmapi-minimal)

Gerd

Hi Ticker

Not sure if relevant, but note in this case assertion occurs while
compiling the tile, not the index. In fact, --index is not included in
the command.
