MacOS C++ coverage: preserve GCOV_PREFIX_STRIP On MacOS, setting GCOV_PREFIX_STRIP to 3 is generally incorrect. This setting works on Linux, because we set PWD=/proc/self/cwd/, which makes all paths have a fixed 3-segment prefix. However, this is not possible on MacOS. On MacOS, the correct setting depends on the path to the exec root or the sandbox root (if sandboxing is enabled). On my machine, the proper value is 10. While this change doesn't fix the underlying issue, at least it allows users to work around it without having to modify and compile Bazel from source. Related to #10457. PiperOrigin-RevId: 291701562
{Fast, Correct} - Choose two
