Hi, We are having some serious problems after we upgraded from C++14 to C++17 on an Jetson TX2 ARM device. Our system tests started to behave differently and fail.
It seems that when our application uses a library (also developed by us) some data gets corrupted when delivered to a class constructor. For example, the .second of and std::pair<float> appears to be the .first and the .second is garbage. This is deterministic, but different tests are failing depending on the combination: library C++17/C++14 <-> application C++14/C++17. This is on Ubuntu 18.04 and gcc version 7.5.0 (Ubuntu 7.5.0-3ubuntu1~18.04). Nothing like this happens on Intel. So: ARM, C++14: OK Intel, C++14: OK ARM, C++17: FAIL Intel, C++17: OK Any ideas what could cause this? I know this is a bit vague, but this a commercial, closed-source application so I cannot yet give any other information.
