c++: default mem-init of array [PR103946]
In the patch for PR92385 I added asserts to see if we tried to make a vec_init of a vec_init, but didn't see any in regression testing. This testcase is one case, which seems reasonable: we create a VEC_INIT_EXPR for the aggregate initializer, and then again to express the actual initialization of the member. We already do similar collapsing of TARGET_EXPR. So let's just remove the asserts. PR c++/103946 gcc/cp/ChangeLog: * init.c (build_vec_init): Remove assert. * tree.c (build_vec_init_expr): Likewise. gcc/testsuite/ChangeLog: * g++.dg/cpp0x/nsdmi-array1.C: New test.
