when using -gdwarf-2
Product: clang
Version: trunk
Platform: Macintosh

Log of clang run
The following program crashes clang r161317 when compiled with option
-gdwarf-2:
template <typename>
struct unique_ptr {
unique_ptr() {}
};
template <unsigned>
struct Vertex {};
//static void crash() // Compiles
void crash() // Asserts
{
unique_ptr<Vertex<2>[]> v = unique_ptr<Vertex<2>[]>();
}
This results in (full log attached):
% ~/LLVM/build/Release+Asserts/bin/clang++ -c -gdwarf-2 -v clang.cpp
clang version 3.2 (trunk 161317)
[...]
Assertion failed: (D && "Cannot get layout of forward declarations!"), function
getASTRecordLayout, file
/Users/rynnsauer/LLVM/llvm/tools/clang/lib/AST/RecordLayoutBuilder.cpp, line
2384.
Without option -gdwarf-2, the code compiles correctly.
The bug already exists in clang r160613.
