I tested again on a Vista machine with --max-jobs=1. The output was
fine: all files were generated.

I then tested on a Mac OS X (Intel) machine. The patch had more or
less the same behaviour: without --max-jobs=1, files were skipped;
with --max-jobs=1 all files were generated.

I logged to file, and then grepped the log files for the map compile
information. The log only indicated that the maps were started and
finished. Tiles which were not generated were also not mentioned in
the log.

The following is an excerpt where the compilation skips from 63240015
to 63240025.

I hope this can help you with finding the cause of the error. Please
let me know if I can perform other tests or provide further
information.

Cheers.
