Bug ID: 28183
Summary: clang crashes on C++11 code with invalid member
initializer: Assertion `AddressOfExpr->getType() ==
Context.OverloadTy' failed
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: C++11
Assignee: unassignedclangb...@nondot.org
Reporter: s...@cs.ucdavis.edu
CC: dgre...@apple.com, llvm-bugs@lists.llvm.org
Classification: Unclassified
The current clang trunk crashes when compiling the following C++11 test case on
x86_64-linux-gnu in both 32-bit and 64-bit modes.
It seems to affect all clang versions since as early as 3.1.
