for previous discussion.
The FreeBSD base system relies on `extern "C++"` in at least the libcxxrt
version script. In FreeBSD we have the ability to replace all of these with the
mangled names if necessary as a workaround, but I suspect this will be a
problem for other third-party software so opening this bug to track.
e.g. from FreeBSD libcxxrt's Version.map:
CXXABI_1.3 {
global:
...
extern "C++" {
# Type info classes and their destructors
"__cxxabiv1::__array_type_info";
"__cxxabiv1::__array_type_info::~__array_type_info()";
...
};
...
};</pre>
