Hi Gerd Our messages crossed. I'll investigate However SimpleRouteTest just checks on the sizes of TRE and RGN; likewise GmapsuppTest, but SimpleTest is more interesting. Ticker On Sat, 2023-06-03 at 09:09 +0000, Gerd Petermann wrote:
Hi Ticker,
thanks for the patch. Some unit tests need changes. Please check if my changes are plausible. Something might be wrong on my system because SimpleRouteTest failed also without your patch.

Hi Gerd & Carlos
I've found the problem and attach a patch which reduces the Subdivision line limit to 254.
Subdivisions/areas have a set of limits, one of which was <= 255 lines. These lines can be of any type including roads. When --route, a reference to each line/road part is created, but these are numbered from 1, so the 255th line in a SubDivision is numbered 256 as a road segment and this can't be represented as a byte in the NET structures.
It looks like this problem has always been there, but is most likely to manifest itself in areas with mostly roads.
