gcc 4.4, 4.5 and 4.6 (bull) shows the same problems and same workaround
(using function).
gcc 4.4.7 (super) shows the same problems and same workaround (using
function).
gcc 4.8.3 (well) shows the same problems and same workarounds (function
or vtype).
gcc 4.9.1 (super) shows the same problems and same workarounds.
This indicates the problem was fixed between 4.9.1 and 4.9.2.
The only thing I find in changes between 4.9.1 and 4.9.2 is
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=63530 (in case this is a
variant of the problem).
