Summary of Problem

While playing with ForwardModeAD, a package I'm writing, I hit the following internal compiler error

Skipping registry update since no dependency found in manifest file.
/home/lferrant/ForwardModeAD/example/example1d.chpl:12: internal error: RES-PRE-OLD-2900 chpl version 1.26.0
Note: This source location is a guess.

Internal errors indicate a bug in the Chapel compiler ("It's us, not you"),
and we're sorry for the hassle.  We would appreciate your reporting this bug --
please see https://chapel-lang.org/bugs.html for instructions.  In the meantime,
the filename + line number above may be useful in working around the issue.

compilation failed for example1d.chpl

My lucky guess would be that it has to do with lambda functions, but I'm not sure. Please feel free to change this issue name to be more informative/accurate.

Steps to Reproduce

Source Code:

The code is also available in the example folder of the package here

use ForwardModeAD;

proc f(x) {
    return x ** 2 + 2 * x + 1;
}


var y = derivative(lambda(x : DualNumber) {return f(x);}, 1.0);
writeln(y);

proc df(x) {
    return derivative(lambda(t : DualNumber) {return f(t);}, x); // this is line 12
}

var z = df(1.0);

Compile command:

mason build --example (also chpl example/example1d.chpl -M src/ gives the same outcome)

Execution command:

N/A
