[clang++] Attribute after last parameter at llvm::VerifierPass::run(llvm::Function&, llvm::AnalysisManager<llvm::Function>&) #112142
Description
This testcase is generated by a fuzzer.
Compiler Explorer: https://godbolt.org/z/K4zjYT7nT
This valid code will crash on Clang Assertion Trunk. It seems that this goes back to clang-14:
class A {
public:
void f();
};
void g() {
void *Af = __builtin_function_start(&A::f);
}Stack dump:
Attribute after last parameter!
ptr @_ZN1A1fEv
fatal error: error in backend: Broken module found, compilation aborted!
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
