Hi,   I'm trying to bypass some weird filtering by my email provider, so please forgive me if this report comes duplicated. Following command produce good mapset for Mapsource:

mkgmap --code-page=1252 --route --index --bounds=bounds 29624847.osm.pbf 29624849.osm.pbf 29624850.osm.pbf This command creates bad mapset: mkgmap --code-page=1252 --route --index --bounds=bounds 29624849.osm.pbf 29624847.osm.pbf 29624850.osm.pbf The only difference is changed order of input pbf files. Bad mapset crashes Mapsource, when trying to send map to GPS. Mapsource gives information about error in MDR_TRIM_ADDR.CXX, which suggest mapset index. I have compared output files for both compilation. Index *_mdr.img is very different. Additionally first and second img are different, while third is the same (except compilation time). I think that output img should be the same, regardless of compilation sequence. --  Best regards, Andrzej
