Greetings, LLVM wizards. I am using clang to compile a C++ module, and an ExecutionEngine (MCJIT) to execute a function it defines. That works (or pretends to). However, if I call the module's constructors first: exec_engine->runStaticConstructorsDestructors(false); exec_engine->runFunctionAsMain(function, argvec, NULL); execution still works, but my program crashes when it exits, in __run_exit_handlers(). I can't tell from gdb what exit handler is crashing, but no calls are made to atexit() or on_exit(); al...

...ONST(0xc0008000); a = new BitCastInst(a, PointerType::get(XgetType(Int32Ty), 0), "", bb); Value* data = new LoadInst(addr, "", false, bb); Error: Bitcast requires types of same width 3. Code: Type const *intptr_type = cpu->dyncom_engine->exec_engine->getTargetData()->getIntPtrType(_CTX()); Value* ptr = new IntToPtrInst(a, intptr_type, "", bb); Value* data = new LoadInst(ptr, "", false, bb); Error: Segmentation fault Any person can give me some hints for my case?

...ate and generate the native code in parallel with multi-thread. But some various bugs will be triggered. We run the following code in multithread environment: ################## BasicBlock::Create(_CTX(), "dispatch", cpu->cur_func, 0); BranchInst::Create(bb_start, label_entry); cpu->exec_engine->getPointerToFunction ##################3 And cpu variable is stored for every thread.

...a segfault.
