Complete log of clang run
The following C++1y program crashes clang r182233 during code generation when
being compiled with -gdwarf-2:
template <typename T>
struct Foo {
static auto bar(int i) { return i; }
static auto bar(long l) { return l; }
};
int main()
{
Foo<bool>::bar(1);
}
This results in (full log attached):
% % ~/LLVM/build/Release+Asserts/bin/clang++ -std=c++1y -gdwarf-2 clang.cpp
Assertion failed: (!isNull() && "Cannot retrieve a NULL type pointer"),
function getCommonPtr, file
/Users/rynnsauer/LLVM/llvm/tools/clang/lib/CodeGen/../../include/clang/AST/Type.h,
line 547.
[...]
clang version 3.4 (trunk 182233)
Target: x86_64-apple-darwin10.8.0
The code compiles successfully without -gdwarf-2.</pre>
