[Bug libstdc++/89464] shared_ptr_base.h: error: '__tag' was not declared in this scope (gcc-8.3.0 regression?)
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=89464 --- Comment #4 from Andrew Pinski --- The problem is in https://github.com/Silicondust/libhdhomerun: hdhomerun_os_posix.h Which does: #if !defined(alignas) #define alignas(n) __attribute__((aligned(n))) #endif That is wrong.
