Commit: 5ca302cb0cb40506e1f8a5f22e9baa3738ab4a58 Author: Dalai Felinto Date: Tue Jul 16 22:23:43 2019 -0300 Branches: master https://developer.blender.org/rB5ca302cb0cb40506e1f8a5f22e9baa3738ab4a58
Fix T67078: Crash with vertex slide and multi-objects If one of the objects had invalid selected edges, it would lead to a crash since none of the for loops were checking for whether the edge slide data is valid. We could refactor the macros to create a new FOREACH_TRANS_DATA_CONTAINER_WITH_DATA However we are too close to 2.80 final release so we manually skip them for now. Note: TRANS_DATA_CONTAINER_FIRST_OK cannot be used either for the same reason.
