jemalloc-5.3.0-r1 build.log

This impacts anyone trying to use +jemalloc on packages when building up from the current musl-llvm-openrc stage3. This appears to be a flavor of the issue reported in GitHub jemalloc/jemalloc PR #2338 (I can't post links yet - despite being a long time Gentoo user off and on, I've never needed to register here :) )

For now I've had to just mask the package completely locally, even building with -O0 doesn't fix (not that I expected it would based on the errors, but since other jemalloc errors have been fixed with that, I gave it a shot).

What a compliment! :)

Could you include emerge --info for all of these bugs (+ going forward too)? Thanks!
Comment 2 Alex Fan archtester 2023-02-16 07:40:06 UTC
I can reproduce. musl doesn't have the nothrow attribute on those std malloc functions. Simply removing these attribute on jemalloc should fix it, like what Mac and BSD did.
