Well, this is perfectly clear, because if you just built the compiler,
you didn't compile anything with such a class construction, as the
compiler is written in C, not C++.
But I would expect the such built compiler to also fail building my
test case, doesn't it?

I can't say very much about that, but it seems so that there is
something broken in the C++ frontend on 64 bit systems. I assume some
false assumptions about size of specific data types that are only
correct on some platforms.
I don't have tried on other 64 bit platforms, but for Solaris I can
say that I am able to build both 32 and 64 bit versions of the
testcase successfully with the compiler built itself in 32 bit mode.
But with a compiler built in 64 bit mode, the bug is triggered
independent of the target being 32 or 64 bit.
