Bug ID: 28368
Summary: clang crashes on valid (?) C++11 code with variadic
template: Assertion `StartColNo <= EndColNo && "Trying
to highlight whitespace??"' failed
Product: clang
Version: trunk
Hardware: PC
OS: All
Status: NEW
Severity: normal
Priority: P
Component: C++11
Assignee: unassignedclangbugs at nondot.org
Reporter: su at cs.ucdavis.edu
CC: dgregor at apple.com, llvm-bugs at 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 crashes all clang versions since at least as early as 3.1.x.
