Did you try to run mkgmap with -ea  ? 
The error in BaseCamp looks like a wrong pointer.

If that doesn't help:
The most important changes between r2447 and r2448 are:
1) removeShortArcsByMergingNodes() is only called for ways that are roads
2) In StyledConverter, the (OSM) ways that are roads are processed after all
other (OSM) ways
were processed.

As far as I know the order should not matter, but maybe it does somehow. 
Maybe that rings a bell?
