Yeah, if a compiler bug is suspected, can anybody please open
a bugreport in http://gcc.gnu.org/bugzilla/ with the preprocessed source,
compiler version, flags and how it was configured and some hint in which
function to look for what exactly?  We don't necessarily need a runtime
small reproducer, but if it can be shown in the assembly what has been
reordered and why you think it shouldn't, with the above mentioned input
that ought to be sufficient.  Thanks.
