  Target Milestone: ---

I'm seeing this subtest FAIL with the following in the log on the GCC 12 branch
when configured for the dual-ABI but defaulting to the C++11 ABI.  It works
fine when defaulting to gcc4-compat.  r12-9300-g0a6e26e7979805 removed
a #define to zero here.

correction, I see it when defaulting to the non-C++11 ABI.

Is this really a 12 regression? I think it's failed that way for some time when
using the old ABI, it's just that nobody except me tests it that way :-)

I think it was fixed on trunk by r13-4080-g2b7f0378b915a6 and backported as
r12-9301-g0970eafdc61d75

At least, I don't see a failure for that test since that commit (which is why
it removed the define).

Ah I see the problem, we need to backport r13-4091-g3c54805d03ac1b too. Not
sure why I don't see a failure though.

Backported as r12-9530-g16a76499f916b5 so I hope this is fixed now (I still
can't reproduce it even with a --with-default-libstdcxx-abi=gcc4-compatible
build).

The failures are gone, thanks.
