My Factorial project [https://github.com/russel/Factorial/tree/master/Chapel](https://github.com/russel/Factorial/tree/master/Chapel) seems to work fine: ```auto |> mason clean 578 lynet:~/Progs/Applications/Factorial/Chapel (git:master) |> mason test Skipping registry update since no dependency found in manifest file. ---------------------------------------------------------------------- Ran 2 tests in 11.393 seconds OK (passed = 2 ) ``` However my Fibonacci project [https://github.com/russel/Fibonacci/tree/master/Chapel](https://github.com/russel/Fibonacci/tree/master/Chapel) fails to build: ```auto |> mason test ./MasonUpdate.chpl:90: error: halt reached - argument to ! is nil ``` I can however guarantee that the code is good: ```auto |> scons scons: Reading SConscript files ... scons: done reading SConscript files. scons: Building targets ... chpl -o Fibonacci_Test --main-module Fibonacci_Test src/Fibonacci.chpl test/Fibonacci_Test.chpl ./Fibonacci_Test positive_arguments() Flavour: OK ====================================================================== ---------------------------------------------------------------------- sequence_positive_arguments() Flavour: OK ====================================================================== ---------------------------------------------------------------------- negative_arguments() Flavour: OK ====================================================================== ---------------------------------------------------------------------- sequence_negative_arguments() Flavour: OK ====================================================================== ---------------------------------------------------------------------- scons: done building targets. ``` ---

@Russel - Thanks for reporting. Just to confirm, are you using Chapel 1.22.1 or 1.23.0 for this test? I noticed the Fibonacci test does not have a `Mason.toml` which may be the cause of this issue. Can you try running `mason init` in the package directory to generate a `Mason.toml`? I was not able to reproduce the error you are getting by running `mason test` in `Fibonacci/Chapel` on the master branch of your repository with Chapel 1.22.1 or 1.23.0. ---

Mason 1.23.0 built from source via the LinuxBrew formula. I had a Mason.toml, it just wasn’t committed to the repository. Sorry about that. Should be fixed now. Problem remains. ☹ ---

Looks like this is a bug in mason that triggers when no `[dependencies]` table exists. You can work around it for now by adding an empty `[dependencies]` section to your `Mason.toml`. I can file an issue on this. Thanks for reporting. ---

@ben-albrecht Seems to be the issue. Thanks for spotting that. As you say add the dependencies paragraph and it all works. 🙂 ```auto |> mason test Skipping registry update since no dependency found in manifest file. ---------------------------------------------------------------------- Ran 4 tests in 11.456 seconds OK (passed = 4 ) ``` ---

FWIW, this bug is now fixed on master: [https://github.com/chapel-lang/chapel/pull/16602](https://github.com/chapel-lang/chapel/pull/16602) ---

As the LinuxBrew formula does not seem to allow installing from HEAD, I’ll have to wait for the next release (1.23.1 perhaps?).
