Hi Tushar, When testing this stuff on a few different platforms, I ran into a switch statement in llvm that returned an empty std::function<> that would throw std::bad_function_call like that, on architectures other than (IIRC) x86 and ARM: https://www.postgresql.org/message-id/CAEepm%3D39F_B3Ou8S3OrUw%2BhJEUP3p%3DwCu0ug-TTW67qKN53g3w%40mail.gmail.com I'm not sure if you're seeing the same problem or another similar one, but I know that Andres got a patch along those lines into llvm. Maybe you could try on a more recent llvm release?
