A clean build can reproduce the problem locally.

I can reproduce.

[mscdex]

Is it only a problem with debug mode (e.g. is it just the -O0 causing it)?

[mscdex]

Also is this limited to clang? Everything seems to have passed for the debug build on Linux arm64 with gcc.

[targos]

Yes, it only affects debug mode. I don't have gcc installed on my mac.

The same question

[xtx1130]

Is there any progress on this issue, or is there any other way for me to compile the main branch codes except --debug?

[mscdex]

@xtx1130 Feel free to temporarily apply this patch. The upstream dependency has a different solution in the works.
