Bug ID: 19993
Summary: clang crashes on invalid code
Product: clang
Version: 3.4
Hardware: PC
OS: Linux
Status: NEW
Severity: normal
Priority: P
Component: C++11
Assignee: unassignedclangbugs at nondot.org
Reporter: llvm-bugs at skybert.org
CC: dgregor at apple.com, llvmbugs at cs.uiuc.edu
Classification: Unclassified

the run script
This simple thing makes clang crash:
-----
class test
{
public:
static int bob = delete;
};
-----
Removing 'static' removes crash.
# clang++ -std=c++11 test.cpp
test.cpp:4:22: error: only functions can have deleted definitions
static int bob = delete;
