SUMMARY: UndefinedBehaviorSanitizer: undefined-behavior src/core/bytecode.c:152:72 in

I confirmed similar (although not the same) errors on GCC on Linux with the undefined behaviour sanitiser turned on.

pyrmont commented 1 month ago

Sorry, I've updated the original post with more fulsome output after noticing that running make test with the sanitiser on on macOS produces more errors. The issue is not simply restricted to src/core/bytecode.c as previously stated.

pyrmont commented 1 month ago

The output when running with the sanitiser on on Linux is slightly different to macOS. Here's what I get:

In case it helps, on macOS, I'm running Apple clang version 16.0.0 (clang-1600.0.21.4). On Linux, I'm running cc (GCC) 13.2.0.

I no longer see the "runtime error..." output when I try the aforementioned steps on a checkout of https://github.com/janet-lang/janet/commit/771956b5b631fc31679455ad0aef332a8a64a401.

pyrmont commented 1 month ago

I no longer see it on Linux, either.

On macOS, the flag causes a warning related to the (int? 8589934592) call in test/suite-codelib.janet but that seems like a warning that's acceptable to ignore given the point of this test is to ensure Janet correctly identifies this as not an int.

I'll mark this as closed. Thanks for such a responsive fix.
