<pre>Thanks for the report.
I believe that this is a duplicate of
<a class="bz_bug_link
bz_status_NEW "
title="NEW --- - num_get::do_get(in, end, double) broken if double is followed by character"
href="show_bug.cgi?id=17782">http://llvm.org/bugs/show_bug.cgi?id=17782</a>.
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.
