--- Comment #10 from Jakub Jelinek ---
I guess on Linux nothing ever calls __cxa_rethrow_primary_exception, so it
isn't a big deal that libasan provides a wrapper for it.
If you want to introduce ASAN_HAS_CXA_RETHROW_PRIMARY_EXCEPTION, it would

--- Comment #6 from Iain Sandoe ---

As Rainer points out, the libsupc++ implementation does not provide
cxa_rethrow_primary_exception whereas the libc++-abi.dylib has it.
For the macOS implementations of
