Hi,
I have a question regarding bug 45106
(http://gcc.gnu.org/bugzilla/show_bug.cgi?id=3D45106). I know it was
closed as invalid, but I have a product, which relies on such
typecasts. I noticed that when I compile it with g++ version 4.4, it
crashes, but when I use g++ version 4.7 everything seems to work. My
question is if there were some changes regarding these typecasts and I
can rely on this in g++ 4.7 or whether this is just coincidence and I
need to rewrite the code.
Thank you
Pavel

I don't think GCC was changed to support that intentionally, the code
is still invalid and not guaranteed to work.
