Your patch on top of Geert's still compiles fine for me with gcc-4.7.3.
However, I'm not sure how specific we can be on the versions.
/me goes to test a few more compilers... OK...
ICE: 4.7.1, 4.7.3, 4.8.3
OK: 4.6.3, 4.9.2, 4.9.3
The diff below[2] on top of yours compiles fine here and at least covers
the compilers I *know* to trigger the ICE.
