Some more information. mkgmap is called with these options:
'--max-jobs=1'
'--style-file=radkarte'
'--overview-mapnumber=59420000'
'--overview-mapname=59420000'
'--series-name=OSM_Radkarte'
'--product-id=1'
'--family-id=5942'
'--family-name=OSM Radkarte 13.01.2011'
'--country-name=Deutschland'
'--country-abbr=DE'
'--latin1'
'--code-page=1252'
'--add-pois-to-areas'
'--adjust-turn-headings'
'--drive-on-right'
'--check-roundabouts'
'--ignore-maxspeeds'
'--ignore-turn-restrictions'
'--location-autofill=1'
'--preserve-element-order'
'--remove-short-arcs=3.3'
'--road-name-pois'
'--show-profiles=1'
'--net'
'--route'
'--gmapsupp'
'--tdbfile'
'--index'
'--nsis'
'M0001736.TYP'
'-c'
'/home/osm/build/template.args'

The output has some unusual warnings/errors:

The "Area too small to split at" messages were seen bevor the problem
