[mkgmap-dev] Unit tests in trunk fail

Sun Jan 5 11:37:09 GMT 2014

Hi Gerd,

I think I found the problem:

// check if merging would create a closed way - which should not
// be done (why? WanMil)
if (cStart == cOtherEnd) {
    return false;
}

The RoadMerger avoids to create closed roads. In case the roads are not 
merged in exactly the same order this is the reason for different merge 
results due to roundabouts. In case a roundabout is divided in multiple 
ways the number of merged ways is random.

At the moment I have no time to check that more in detail but I think 
the code listed above can be removed.
