<pre>This line:
cout << regex_match("bbb", regex("a*|b*")) << endl;
should print 1, but prints 0 instead (with <regex> from libc++). It's not
operator hierarchy issue because "a*|(b*)" doesn't work either.
libstdc++ gives the right output.
My platform: Debian Jessie, libc++1 version 1.0~svn205159-1; clang version
3.3-16</pre>
