You are volating C/C++ aliasing rules even with the casts to void*. What
matters is the type of accesses.

In this program, I am taking a 64-bit double and reinterpreting it as a 64-bit
long long. I am then reinterpreting that as a 64-bit double again. The
expected output of the program is "1", but when compiling with -O2, the answer

GCC 4.5 appears to fail when using sizeof(member-of-templated-type) inside a
template parameter.
I have tested the Debian gcc-snapshot 20090923-1 amd64 package, 20091010-1
i386, and Ubuntu gcc-snapshot 20091018-1 amd64. All exhibit the same behavior.
g++-4.4 works fine, however.
