<pre>I'm using all packages from a Debian testing installation.
The combination of clang++-9 && address sanitizer && gold linker gives me a
linker warning (potentially turned into an error by linker flag) about not
being able to export the local symbol `__asan_extra_spill_area`.
$ cat main.cpp
int main(){}
$ /usr/bin/clang++-9 -fsanitize=address -fuse-ld=gold main.cpp
/usr/bin/ld.gold: warning: Cannot export local symbol '__asan_extra_spill_area'
Only the specific combination of clang 9/10, address sanitizer and gold linker
seems to be broken:
- Changing compiler solves the issue: g++ 9.2.1 and clang++-8 are ok, clang++-9
and clang++-10-rc2 exhibit the issue
- Changing the sanitizer solves the issue: undefined, memory and thread are ok
- Changing the linker solves the issue: bfd and lld-9 are ok</pre>
