Description Vladimir Marko 2014-06-12 11:32:11 UTC 
Test case:

struct S {
  constexpr S() { }
};

constexpr S s[][1] = {
    { S() }
};

Bogus error:
test.cc:7:1: error: array must be initialized with a brace-enclosed initializer

Reproduced with gcc 4.6.3 on host (x86_64-linux-gnu) and gcc 4.8.0 from AOSP prebuilts (x86_64-linux-android).
Comment 1 Vladimir Marko 2014-06-12 13:43:45 UTC 
Fails with gcc 4.9.0 from AOSP prebuilts (aarch64-linux-android).
Comment 2 Daniel Krügler 2014-06-13 21:39:31 UTC 
The same error exists in 4.10.0 20140612 (experimental)
Comment 3 Paolo Carlini 2014-08-29 08:33:15 UTC 
This works in current mainline, I'm adding the testcase and closing the bug.
