Hi Alberto, Thanks for the minimal crashing program. The crash wasn't straight forward to pinpoint the cause but eventually I traced it back to the the ObjectCache taking a ref_ptr<Options> when search for entries in the ObjectCache. To avoid this I wrote a ObjectCache::find(..) method that doesn't create a temporary ref_ptr<> to the Options being passed in. This fix is checked in the OpenSceneGaprh-3.6 branch and master.
