            Bug ID: 49767
           Summary: Dumping AST to json triggers assertion with VLA array
                    in function body
           Product: clang
           Version: trunk
          Hardware: PC
                OS: All
            Status: NEW
          Severity: normal
          Priority: P
         Component: C++

Dumping AST to json, using the parameter -ast-dump=json, causes an assertion on
clang:

clang++: /root/llvm-project/clang/lib/AST/ItaniumMangle.cpp:4968: void
{anonymous}::CXXNameMangler::mangleFunctionParam(const clang::ParmVarDecl*):
Assertion `parmDepth < FunctionTypeDepth.getDepth()' failed. 

This is a minimum failing example on godbolt:
