patch from upstream

There seems to be a crash related to the allocate buffer on musl being too small. Upstream bug report is , the patch has been landed in the 49 branch. To me it seems reasonable to apply it to both the 47 branch as well as to the upcoming 48 branch.

Upstream backported the fix to the upcoming 48 branch, so the amount of work to be done for 47 is minimal. Are you willing to add the patch to the tarball or not?

I'll look at this once I get 48.0_beta3 to build.  There's still a couple of weeks before 47.0 will be dropped so I think it's worth pursuing yes.

I just checked 47.0.1, it is still affected. The attached upstrem patch heals the segfault, and can be applied without any itchy backporting. Please close this bug if you managed to push the patch to the overlay and have it in the ebuild. Thanks.

upstream fixed this in 48.0, the current esr branch is not affected.
