--- Comment #1 from Marshall Clow (home) <mclow.lists at gmail.com> ---
Thanks for the report.

I believe that this is a duplicate of
http://llvm.org/bugs/show_bug.cgi?id=17782.

What's happening here is that libc++ is attempting to parse this as a hex
float.
[ You have to dig into the C standard to find out about that.. ]

If you change the string to "zyx", both libc++ and libstdc++ print 0.

I've added your example to that bug.
