Hi all, starting from a few weeks I started observing these crashes while using the Python wrapper STPyV8 [1]. I am the lead developer of STPyV8 and no relevant changes were introduced recently other than updating the V8 version to use in the building process. This trace was generated using V8 12.2.281.19
