Hi Volker,

Thanks for your report. However, I cannot reproduce it.

I'm getting a distance back of 266333, which is the correct value. To be 
sure I also checked for 1.48 and it is still OK for me.

I also inspected the code and find nothing strange for polygons or a 
minimal check of points (first thought of that) there.

So... are you sure?

Attached my program to verify this.
