Suggested patch
The problem appears in revision 200588 in version 4.9. I have attached a
one-line patch that fixes it.
In method "maybe_deduce_size_from_array_init()" in decl.c, the loop on line
4839 should break immediately after "failure" is set to 1. All the iterations
after "failure" set to 1 do not perform any useful work, at best they just set
"failure" again to 1.
