[Libunwind-devel] compile error in tests: cannot make copy relocation for protected symbol '_Ux86_64_local_addr_space'

[Milian Wolff]

Hey all,

I just updated to latest master (haven't done so in a long time), and started 
from scratch to build with a clean build folder (i.e. out of source). 
Everything is peachy until the tests get build:

~~~~~~~~~~~~~~~~~~~~~~
Making all in tests

~~~~~~~~~~~~~~~~~~~~~~

I have found https://sourceware.org/bugzilla/show_bug.cgi?id=17711 which makes 
it sounds as if this has long been fixed... Has anyone a clue what's going on? 
This is on ArchLinux with gcc and ld of the following versions:

Configure line I used is:

~/projects/src/libunwind/configure --prefix $HOME/projects/compiled/other/ --
enable-debug-frame --enable-minidebuginfo --enable-coredump --enable-ptrace --
enable-setjmp 

Thanks
