Related to #4136.

@maurolacy As first time contributor your PR required some approval for CI workflow. You have to wait until one of the meinteiners does it.

OK. It turns out I couldn't reproduce this in main. It only fails in the version_101 tag (under alpine). So, it seems this is already a solved issue.

Will add a couple of scripts and instructions with the path for reproduction.

Question would be then: when version_102 is going to be released?

[maurolacy]

Bug triggers when building statically on alpine (build script added for reference), but only in the version_101 tag.

If --debug is added, segfault disappears. ?-) Dangling pointers having fun I guess.

If I build a static binary based on the alpine build, but in debian, wasm-opt segfaults when launched without args. More dangling pointers.

Anyway, it seems this is solved / couldn't reproduce in the main branch. Close and wait for 102 I guess?

Thanks for confirming. Yes, I think we can just release 102 now, I'll open a PR.

Ok, 102 was tagged and CI is working on builds.
