Summary of Problem
It seems like there is a compiler bug if I have a default initial value for one field of a class but not another. But I am not sure. I found a quick workaround, so this is not a stopping issue for me.
Steps to Reproduce
Source Code:
use IO;
config const inputFile = "testin3.txt";
// open a file and create a reader
var f = open(inputFile, iomode.r);
var reader = f.reader();
// A 5-digit binary class
class FiveDigitBinary {
var digit : [1..5] int;
var next : FiveDigitBinary? = nil; // line 31
}
The code modification that did not run into the compiler bug was as follows:
// A num-digit binary class
class BinaryDigits {
var digit : [1..numDigits] int = 0;
var next : owned BinaryDigits? = nil;
}
It also worked before changing the 5 to numDigits.
Execution command:
$ chpl day3-binary.chpl
day3-binary.chpl:31: internal error: UTI-MIS-0935 chpl version 1.26.0
