Bug ID: 28031
Summary: clang crashes on valid C++ code with -std=c++11 or
-std=c++14: Assertion
`isLambdaCallOperator(Frame->Callee) &&
(VD->getDeclContext() != Frame->Callee ||
VD->isInitCapture()) && "missing value for local
variable"' failed
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 crashes when compiling the following valid C++ test
case with -std=c++11 or -std=c++14 on x86_64-linux-gnu in both 32-bit and
64-bit modes.
It compiles fine with -std=c++98 and -std=c++03.
This is a regression from 3.8.x.
