Bug ID: 30440
Summary: crash on valid c++ code on x86_64-linux-gnu with
-std=c++14 (void
{anonymous}::CXXNameMangler::mangleFunctionParam(const
clang::ParmVarDecl*): Assertion `parmDepth <
FunctionTypeDepth.getDepth()' failed.)
Product: clang
Version: trunk
Hardware: PC
OS: Windows NT
Status: NEW
Severity: normal
Priority: P
Component: C++
Assignee: unassignedclangbugs at nondot.org
Reporter: chengniansun at gmail.com
CC: dgregor at apple.com, llvm-bugs at lists.llvm.org
Classification: Unclassified
This should be a recent regress. clang-3.8 does not crash.
