Bug ID: 28047
Summary: clang crashes on valid C++ code: Assertion `parmDepth
< FunctionTypeDepth.getDepth()' 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 on x86_64-linux-gnu in both 32-bit and 64-bit modes.
This is a regression from 3.8.x (it also crashes at least 3.5.x to 3.7.x).
