Extended Description

Codegen crashes on this:
static int a[10];
static int a[] = { 1, 2, 3 };

because sema is saying the type of the second 'a' is int[3] instead of int[10]. Apparently sema should merge the previous int[10] into the array type before analyzing the initializer.

Testcase from Anders.

[llvmbot]

This seems to be fixed. Where is the best place to put a testcase?

[lattner]

probably test/Sema/init.c, thanks!

[nunoplopes]

still not fixed in HEAD.

[efriedma-quic]

Fixed in r62947.
