A memory error was encountered executing np in the main function.
Below is my code, I am sure that the pass in the runTimer function is being executed properly, but on return to the main function is a memory error. And the memory error is different for different IR files (sometimes malloc(): unsorted double linked list corrupted , sometimes Segmentation fault (core dumped) ).
extern "C" void runTimer(llvm::Module &M){
llvm::legacy::PassManager lpm;
lpm.add(llvm::createLowerSwitchPass());
lpm.run(M);
PassBuilder PB;
FunctionPassManager FPM;
ModulePassManager MPM;
ModuleAnalysisManager MAM;
FunctionAnalysisManager FAM;
CGSCCAnalysisManager CGAM;
LoopAnalysisManager LAM;
// Register analysis passes with the managers
PB.registerModuleAnalyses(MAM);
PB.registerFunctionAnalyses(FAM);
PB.registerCGSCCAnalyses(CGAM);
PB.registerLoopAnalyses(LAM);
PB.crossRegisterProxies(LAM, FAM, CGAM, MAM);
FPM.addPass(timer::LowerSelect());
FPM.addPass(timer::BasicBlockTimer());
MPM.addPass(llvm::createModuleToFunctionPassAdaptor(std::move(FPM)));
MPM.run(M, MAM);
}
int main(int argc, char **argv) {
// Initialize LLVM
InitLLVM X(argc, argv);
cl::opt<std::string> InputFilename(cl::Positional, cl::desc("<input IR file>"), cl::init("-"));
cl::ParseCommandLineOptions(argc, argv, "LLVM IR File Reader\n");
LLVMContext Context;
SMDiagnostic Err;
std::unique_ptr<Module> M = parseIRFile(InputFilename, Err, Context);
if (!M) {
WithColor::error(errs(), argv[0]) << "Error reading IR file: " << InputFilename << "\n";
Err.print(argv[0], errs());
return 1;
}
runTimer(*M);
std::cout << "Timer pass finished!" << std::endl;
return 0;
}

This error occurs when I use llvm::createModuleToFunctionPassAdaptor, without llvm::createModuleToFunctionPassAdaptor everything works fine.
