Hello

> I have no clue.  But what does GCC do when you try the following?

I tried gcc 4.2 and 4.3 on Linux on a Intel(R) Core(TM)2 CPU         T5500 
@ 1.66GHz the version of boost is 1.36.

It crashes. Prehaps its some gcc bug. I have no real idea what 
is the problem. As I said: I send the same report to the gcc team. But I 
think it is also interesting for the boost team.
