Extended Description

GCC 4.2 (and other versions) accept this C testcase without error:

void p = ((void)&((char*)0)[0]);

llvm-gcc-4.2 rejects it with this message:

t.c:1: error: initializer element is not constant

This is reproducible on both trunk and the 2.4 prerelease.

This prevents llvm-gcc from compiling SQLite version 3.6.4,
which is the current version at this time. The specific
error message is:

sqlite3.c:12108: error: initializer element is not constant
