| - Even when using LLVM 10.0.0, I would still get my segmentation fault when using this utility... It took me quite a long time to figure out what was happening but I finally realize this was because **somehow, the code I'm generating in my JIT compiler is not registering a destructor with the "%%__cxa_atexit%%" handler, but instead, with the legacy/obsolete "atexit" handler**. Unfortunately, I have no real idea why (yet). | - Even when using LLVM 10.0.0, I would still get my segmentation fault when using this utility...

| <note>I've tried various setups with the command line arguments "-fno-use-cxa-atexit", "-fuse-cxa-atexit", "-fregister-global-dtors-with-atexit", but none of these really helped to use the cxa_atexit handler. But as a remainder, don't forget that I'm on windows 10 platform and using all the ms compatibility flags for Visual Studio... maybe that could be part of the explanation [Or maybe I just need to try harder...]</note> | <note>I've tried various setups with the command line arguments "-fno-use-cxa-atexit", "-fuse-cxa-atexit", "-fregister-global-dtors-with-atexit", but none of these really helped to use the cxa_atexit handler.
