[mkgmap-dev] Problem with --index and 812KB _mdr.img files & "warning using default sort"

Wed Mar 16 00:14:32 GMT 2011

1. Could mkgmap clean up broken 812KB mdr_img files if creating crashes 
due to insufficient memory? This is a potential threat as the _mdr.img 
is broken but hard to notice if you don't look at error notices).

2. What does the "warning using default sort" thingy mean. Can it be 
overcome or if not could it be switched off?
