[mkgmap-dev] assertion in mdrx2 in housenumber2 branch

Tue May 5 09:59:12 BST 2015

Hi Steve,

I think I found a bug in the code that exists also in trunk.
See change in r3566. 
The problem occurs when a single map contains two cities with equal name and region/country
e.g.
two times Laubach in Hessen/Germany:
node 104505800,node 240031988

The method() Mdr5.preWriteImpl() sorts all cities and adds
only one entry for these two cities because they are "equal",
but the roads can contain a reference to the other city object.

I do not yet understand why the problem occurs only in the branch.
Is this kind of bad luck?

Hi Steve,

when creating the index for multiple files
I see now an assertion from line 45: 
            assert street.getMapIndex() == street.getCity().getMapIndex() : street.getMapIndex() + "/" + street.getCity().getMapIndex();

I guess the code is not yet prepared for roads with more than one city,
but I don't understand it yet.

Do you have a hint what to change here?

Gerd
