  • owner changed from geos-devel@… to strk
  • status changed from new to assigned

Looks like a stack overflow while infinitely recurring into UnaryUnion? to fix an invalidity. It's indeed a new "feature" to reduce the chances of getting invalid results in output.

r3711 in trunk (r3712 for the test) and r3713 in 3.3 branch

  • status changed from closed to reopened
  • resolution fixed deleted

Before fully closing this, I think I saw the test still failing in 3.3 branch (not segfaulting but failing). Looking at it to be sure nothing else got broken. An exception would still be acceptable, but worth checking out why.

I just realized that it was the _original_ XML succeeding (the one attached), not the simplified one I pushed into the repo.

A further tweaked test was committed in r3714 for 3.3 branch and r3715 in trunk.
