           Summary: Resizing array of associative arrays (uint[char[]][])
                    causes infinite loop / hang
           Product: D
           Version: 1.004
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: major
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla@digitalmars.com
        ReportedBy: nick.atamas@gmail.com


The following code produces an infinite loop. When executed "before" is printed but "after" is never reached.

import std.stdio;
int main()
{
        uint[char[]][] fractal;
        writefln("before");
        fractal.length = 10;
        writefln("after");

        return 0;
}

http://www.digitalmars.com/d/arrays.html#associative (under "Properties"): .length         Returns number of values in the associative array. Unlike for dynamic arrays, it is read-only.

So this shouldn't even compile...

uint[char[]][] fractal;

fractal is a dynamic array, so length is not read-only.

Ah, I missed the last brackets. Sorry about that.

This worked just fine in DMD1.0. It was broken recently.

I am currently using a workaround - encapsulating uint[char[]] into a class and making an array of those.

Just stumbled on this when recompiling an older project.
To me dynamic and associative arrays are key features of D.
The bug was introduced with version 1.001.
Therefore increased priority as well as severity and set Version to 1.001.

The bug shows up on upsizing only. Downsizing by assigning to length is possible.

The type `int[int][]' is sufficient to show the bug.

Ouch.  This one just bit me too.
So throw in my "vote" or whatever.
This needs a-fixin' pronto.

Thanks for the workaround suggestion, Nick.
