Bug ID: 27047
Summary: clang crashes on valid C++11 code
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: -New Bugs
Assignee: unassignedclangbugs at nondot.org
Reporter: su at cs.ucdavis.edu
CC: llvm-bugs at lists.llvm.org
Classification: Unclassified
The current clang trunk (as well 3.6.x and later) crashes when compiling the
following valid C++11 test case on x86_64-linux-gnu in both 32-bit and 64-bit
modes.
This is a regression from 3.5.x.
