Outputting a @ccallable function to an object file broken on master #35014

Closed KristofferC closed 4 years ago

KristofferC commented 4 years ago

MWE from test failure in PackageCompiler.jl

# callable.jlj
Base.@ccallable function f()::Cint
    return 0
end
run(`$(Base.julia_cmd()) --startup=no --output-o=sys.o ccallable.jl`)

prints:

Assertion failed: (Val && "isa<> used on a null pointer"), function doit, file /Users/kristoffercarlsson/julia/usr/include/llvm/Support/Casting.h, line 105.
