Fixed on trunk.  I'll backport it for 4.6.4 as it is latent on the branches.

Thanks. I reported the problem because I thought it could
hit somewhere else and I have some code that way, that was
working since gcc 4.4, but the proper syntax to initialize
the local variable should be, in the sample test case:
vl_t w = {x,x};
what should make it easier for the compiler to understand
what is being done.

Re-open so I don't forget about the backporting.
