Sorry, I should have been more explicit. I saw that, but my question is: what
is the underlying problem that triggers the assert? The comment is not much
help to me. And more specifically: what could a target be doing wrong that
would make an early stage of the compiler fail like this on what seems like a
pretty straightforward source file?
Many of the other libstdc++ bits compile just fine, as do plenty of testsuite
cases and some test files of my own.
