Summary: Clang crashes with g++ 4.6 header files
Product: clang
Version: 2.9
Platform: PC
OS/Version: Linux
Status: NEW
Severity: normal
Priority: P
Component: Frontend
AssignedTo: unassignedclangbugs at nondot.org
ReportedBy: thanhdk at gmail.com
CC: llvmbugs at cs.uiuc.edu
When I try to compile a very simple c++ file (just declare a new stl vector)
and compile with clang 2.9:
clang -I. -I/usr/include/c++/4.6 -I/usr/include/c++/4.6/x86_64-linux-gnu/.
-I/usr/include/c++/4.6/backward -I/usr/lib/gcc/x86_64-linux-gnu/4.6.1/include
-I/usr/local/include -I/usr/lib/gcc/x86_64-linux-gnu/4.6.1/include-fixed
-I/usr/include/x86_64-linux-gnu -std=c++0x hello.cc
Here is the source file:
#include <vector>
using namespace std;
int main()
{
vector<int> v;
return 0;
}
Here's the output from clang:
