> I was able to reproduce the same error with gcc 3.4.6.
> The purpose of the test is to verify the conformance of the <cwchar> header
> WRT namespace cleanliness (i.e., that symbols like struct tm are defined in
> namespace std and not also in the global scope). The test is designed to fail
> at runtime (via assertions) rather than at compile time but it looks like the
> implementation of the test (or maybe even its
> design) is broken. In any case, the fact that the test doesn't compile
> suggests there is a problem with the header.
> The compilation errors for the simple program below confirm this. Can you
> open an issue for this problem and reference this thread in the archive in
> the issue?
> $ cat t.cpp && nice make t
> #include <cwchar>
