Comment (by aar@…):

 Hello,
 get_trapezoids() is affected too, and I can reproduce the issue on any
 Debian Wheezy machine, since that distro uses 4.7.2.  It looks like the
 gcc issue might be http://gcc.gnu.org/bugzilla/show_bug.cgi?id=56125 or
 http://gcc.gnu.org/bugzilla/show_bug.cgi?id=54767


 I think this needs to be reopened and investigated, and some macros need
 to be added to workaround the issue if 4.7.0, 4.7.1 or 4.7.2 is detected.
 While upgrading to 4.7.3 makes the problem disappear, the great popularity
 of gcc 4.7.2 (thanks to Debian Wheezy) raises the need for a built-in
 workaround IMHO.
