Bug ID: 28033
Summary: clang crashes on invalid C++ code: Assertion
`!D->isInvalidDecl() && "Cannot get layout of invalid
decl!"' 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 C++ test case with
on x86_64-linux-gnu in both 32-bit and 64-bit modes.
3.8.x (incorrectly) accepts and compiles the code, while, like the trunk, 3.4.x
to 3.7.x all crash on the same code.
