Cannot use apps created with PackageCompiler that have LLVM.jl in them

General Usage

1

I’m trying to create an app with LLVM.jl in it.
The create_app call runs successfully, but I get an error when I try to run the app itself because the LLVMExtra artifact is apparently not downloaded and set up while the app is getting created.
How can I fix this?

Seems like I am having the same problem as well.

PackageCompiler: compiling incremental system imagejulia: /buildworker/worker/package_linux64/build/usr/include/llvm/Support/Casting.h:269: typename llvm::cast_retty<X, Y*>::ret_type llvm::cast(Y*) [with X = llvm::GlobalVariable; Y = llvm::GlobalValue; typename llvm::cast_retty<X, Y*>::ret_type = llvm::GlobalVariable*]: Assertion isa<X>(Val) && "cast<Ty>() argument of incompatible type!"' failed.
