28696, "nldias", "[Bug]: out intent unable(?) to identify when a real array is passed in lieu of a real", "2026-04-16T18:58:31Z"
Summary of Problem
Description:
What behavior did you observe when encountering this issue?
The compiler reports an internal error
What behavior did you expect to observe?
The compiler should have catched the type mismatch.
Describe the workarounds you've tried, if any.
It is easy to identify the mismatch manually. The error message refers to the
correct line (11; see code below)
Is this issue currently blocking your progress?
No, because it is easy to spot the problem manually.
Steps to Reproduce
Source Code:
const nC = 5;
var xbar,ybar: [1..nC] real;
for C in 1..nC do {
// -----------------------------------------------------------------
// The eigenvalues.
// -----------------------------------------------------------------
var lambda1 = 10.0;
// -----------------------------------------------------------------
// Find the ellipse for each cluster.
// -----------------------------------------------------------------
ErrorTest(lambda1,xbar,ybar);
}
proc ErrorTest(
const in lambda1: real,
out xbar: real,
out ybar: real) {
xbar = lambda1;
ybar = lambda1 + 1.0;
}
Compile command:
chpl outerror.chpl
Execution command:
./outerror
Gives the error
outerror.chpl:11: internal error: AST-FOR-LLS-01346 chpl version 2.8.0
Note: This source location is a guess.
Internal errors indicate a bug in the Chapel compiler,
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.
