Just polling to see if anyone is using aarch64 in uclibc-ng. I created a toolchain from buildroot for some new hardware I got but noticed a lot of segfaulting with c++ applications. Thinking it was possibly a libstdc++ issue I opened a bug report.

But it seems to concluded that uclibc-ng tls support for aarch64 isn't quite there. Some of the segfaulting is fixed if libstdc++ is static linked, but doesn't quite fix all the issues.
