...ors(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(); all exit handlers are installed via __cxa_atexit(). This may or may not be meaningful, but I am forced to compile with -fno-use-cxa-atexit, otherwise clang complains that __dso_handle could not be resolved. Any guidance would be MUCH appreciated. I am at a loss... Also, if you know of a better place to look for help than this mailing list, that...

Hi, Not sure whether this matches your use case, but the Orc-based JIT used in LLI appears to be using `llvm::orc::LocalCXXRuntimeOverrides` (http://llvm.org/doxygen/classllvm_1_1orc_1_1LocalCXXRuntimeOverrides.html) to override `__cxa_atexit`: https://github.com/llvm-mirror/llvm/blob/release_50/tools/lli/OrcLazyJIT.h#L74 https://github.com/llvm-mirror/llvm/blob/release_50/tools/lli/lli.cpp#L631 Best, Matt On 11/23/2017 19:49, Stefan Gränitz via llvm-dev wrote: > Maybe the easiest workaround would be overriding symbol resolution...
