[Bug c++/34295] New: Bad optimization in an inlined method

[dvt at isoft dot fr]

In an inlined method, we cast a double argument into an INT64& : with gcc4.2.1
(not with other versions or compilers), this gives a completely false result
that leads to a crash. To avoid this, we had to create an INT64 on the stach
and to memcpy the double into it, which is much less optimized... Of course, we
compile with full (O3) optimization. With O0, this works.
