Yeah, sorry, I'm a bit baffled about this situation myself. Yesterday
I've opened a one-line PR fix that should address the issue, maybe this
would help. In the meantime I've attached what did work for me as a
workaround -- it essentially just makes the deform function to return
some value. It's ugly, but since call site will ignore that, and it's
only one occasion where LLVMBuildRetVoid is used, maybe it's acceptable.
Give me a moment, I'm going to test this change more (waiting on
rebuilding LLVM, it takes quire a while on my machine :( ), then can
confirm that it works as expected on the latest version.
