Subject Compiler BUG present in Groovy.3.0.0-alpha-1
Date Mon, 16 Apr 2018 16:05:06 GMT
Hi,

I have just recompiled my system using Groovy3.0.0-alpha-1.  The same bug appears at the same
line.


Error message:


Error:Groovyc: While compiling gppDemos: BUG! exception in phase 'class generation' in source
unit 'D:\IJgroovy\gpp\gppDemos\src\demos\nQueensProblem\QueensClient.groovy' At line 67 column

This method should not have been called. Please try to create a simple example reproducing
this error and file a bug report at https://issues.apache.org/jira/browse/GROOVY

Code that causes the problem with the line causing is highlighted:

double doFitness(List <Integer> board) {
    List <Integer> leftDiagonal = new ArrayList(2*N)
    List <Integer> rightDiagonal = new ArrayList(2*N)
    double sum = 0.0D

    for ( i in 1 .. 2*N) {
        leftDiagonal[i] = 0
        rightDiagonal[i] = 0
    }
    for ( i in 1 .. N) {
        leftDiagonal[i+board[i]-1]++
        rightDiagonal[N-i+board[i]]++
    }
    for ( i in 1 .. ((2*N) - 1)) {
        int counter = 0
        if ( leftDiagonal[i] > 1)
            counter += leftDiagonal[i] - 1
        if ( rightDiagonal[i] > 1)
            counter += rightDiagonal[i] - 1
        sum += counter / (N - Math.abs(i-N))
    }
    // target fitness is 0.0
    // sum can be negative so return absolute value
    return Math.abs(sum)
}


Thus  the code compiles with Groovy.2.4.12 but not with other later 2.4 versions, or 2.5 or
the 3.0.0 versions.  I have not tried the 2.6 version.

I have checked the version of Groovy I was using in Eclipse prior to moving to Intellij and
that was 2.4.11.  On moving to Intellij I first started with 2.4.12 then moved to 2.5 at which
point the problem occured.

Hope this helps in trying to find the problem.
