------- Comment #8 from jakub at gcc dot gnu dot org 2009-01-14 15:00 ------- As any call to a nested function with VL return type ICEs (even if the result isn't used) in 3.4.5 through 4.4.0, I doubt this is used very widely.
That said, if we deprecate it now, we'd have to fix it, warning about deprecation and then ICE doesn't make much sense. -- http://gcc.gnu.org/bugzilla/show_bug.cgi?id=21374
