odr-violation.cc revision 86277eb844c4983c81de62d7c050e92fe7155788 
1// FIXME: https://code.google.com/p/address-sanitizer/issues/detail?id=316
2// XFAIL: android
3//
4// We use fast_unwind_on_malloc=0 to have full unwinding even w/o frame
5// pointers. This setting is not on by default because it's too expensive.
