This is a clone of #702 for the 1.8 branch.

@bregma this is the same issue as discussed in https://github.com/libunwind/libunwind/issues/702, would be great to have this in 1.8.2. Issue https://github.com/libunwind/libunwind/issues/702 is tagged for 1.9.0 - patch fix would be better in 1.8 series. Thanks.

This issue is for backporting the patch from the master branch (with a 1.9.0 milestone) to the 1.8 branch (with a 1.8.2 milestone). Github does not allow you to target issues to multiple branches. Nothing goes into a stable release branch without (a) an issue to close and (2) going on to the master branch first.

Ah, thanks @bregma. Looking forward to it.

I see PR #770 was opened to resolve this issue. Are we waiting on something, or could #770 be merged to resolve this issue?

bregma commented 2 months ago

Just waiting for sufficient soak time on the master branch. I'll get to it soon.
