 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.
