I try to use a static llvm::orc::LLJIT instance to manage ir modules, and it aborted when the program exited and deconstruct the LLJIT instance. The code is below. The "foo" module simply "a = a + 100; b = b + 200", and it can execute correctly. If I change LLJIT from static to non-static, it can also exit normly.

class CustomOrcJIT
{
public:
static std::unique_ptr<llvm::orc::LLJIT> J;
public:
CustomOrcJIT(/* args */) {
J = ExitOnErr(LLJITBuilder().create());
}
~CustomOrcJIT() = default;
};
// initialize
std::unique_ptr<llvm::orc::LLJIT> CustomOrcJIT::J = nullptr;
// load and execute
int main(int argc, char *argv[]) {
InitLLVM X(argc, argv);
InitializeNativeTarget();
InitializeNativeTargetAsmPrinter();
CustomOrcJIT jit;
llvm::SMDiagnostic error;
// Compile Module
std::unique_ptr<llvm::LLVMContext> context = std::make_unique<llvm::LLVMContext>();
std::unique_ptr<llvm::Module> module = std::make_unique<llvm::Module>("foo", *context);
StringRef filePath = "foo.ll";
module = parseIRFile(filePath, error, *context);
auto TSM = ThreadSafeModule(std::move(module), std::move(context));
// Load the module.
ExitOnErr(jit.J->addIRModule(std::move(TSM)));
// bind variable
int32_t a = 3;
int32_t b = 4;
ExitOnErr(jit.J->getMainJITDylib().define
(absoluteSymbols(
{
{jit.J->mangleAndIntern("a"), JITEvaluatedSymbol::fromPointer(&a)},
{jit.J->mangleAndIntern("b"), JITEvaluatedSymbol::fromPointer(&b)},
{jit.J->mangleAndIntern("printf"), JITEvaluatedSymbol::fromPointer(&printf)}
})
)
);
// Execute
auto fooAdrr = ExitOnErr(jit.J->lookup("foo"));
void (*foo)() = fooAdrr.toPtr<void()>();
foo();
outs() << "a = " << a << ", b = " << b << "\n";
return 0;
}
Output is below.
> a = 103, b = 204
pure virtual method called

Aborted
However, if I directly declare `static std::unique_ptr<llvm::orc::LLJIT> J = ExitOnErr(LLJITBuilder().create());` in main function and use it, It's correct. So whether it means that LLJIT can not be a static member of class.
