Fix two undefined behavior issues (pipeline/config, elpp) - #10876
Merged
Conversation
pipeline/config: initialize playback_loop We found a UBSan complaint of the value 173 being stored into a boolean in the copy constructor. third-party/easyloggingpp: work around global init order bug The validateFileRolling function is called during the static initialization of an el::Storage, but it tries to access the global el::Storage. Clang compiles this into a branch to ud1. Instead, just skip the function call. PiperOrigin-RevId: 471841322

EasyLogging++ has fixed this too, it seems. I've opened a PR to upgrade to their latest. @riking thanks for the incentive :) I'm going to try to remove the easylogging fix from this PR and then merge it... |

The easylogging patch was the quick-and-dirty method to get our binaries to stop crashing. If you have suggestions for a better patch, I'm willing to explore them.
