I have ran into this issue on 14 as well.
But I cant generate an assembler file without the LLVM crashing
This is the error I get
```
terminate called without an active exception
Aborted (core dumped)
```
and here is the code
```C++
llvm::LLVMContext context;
llvm::Module module("MyModule", context);
llvm::IRBuilder<> builder(context);
// Initialize the target registry etc.llvm::InitializeAllTargets();
llvm::InitializeAllTargetInfos();
llvm::InitializeAllTargets();
llvm::InitializeAllTargetMCs();
llvm::InitializeAllAsmParsers();
llvm::InitializeAllAsmPrinters();
std::string Error;
auto TargetTriple = llvm::sys::getDefaultTargetTriple();
auto Target = llvm::TargetRegistry::lookupTarget(TargetTriple, Error);
module.setTargetTriple(TargetTriple);
if (output.print_llvm == 1)
{
module.print(llvm::outs(), nullptr);
}
if (!Target)
{
std::cout << Error << std::endl;
return;
}
auto CPU = "generic";
auto Features = "";
llvm::TargetOptions opt;
auto TargetMachine = Target->createTargetMachine(TargetTriple, CPU, Features, opt, llvm::Reloc::PIC_);
module.setDataLayout(TargetMachine->createDataLayout());
llvm::legacy::PassManager pass;
llvm::raw_fd_ostream dest(output.output_files[i], EC, llvm::sys::fs::OF_None);
if (EC)
{
llvm::errs() << "Could not open file: " << EC.message();
return;
}
auto FileType = llvm::CodeGenFileType::CGFT_AssemblyFile;
if (TargetMachine->addPassesToEmitFile(pass, dest, nullptr, FileType))
{
llvm::errs() << "TargetMachine can't emit a file of this type";
return;
}
pass.run(module);
dest.flush();
```
I know this is a LLVM error because it works with generating an IR file, compiled binary, and an unoptimized IR file.
