Accessing ceylon.interop.browser.dom.document goes into infinite loop on 1.3.2

As at: http://try.ceylon-lang.org/?gist=5fb85393d1631ea78ecdfff0a79b0d77

The following never completes. Firefox offers to stop the script. Chrome consumes 100% cpu indefinitely. The same occurs with document.getElementById(“someid”).

import ceylon.interop.browser.dom {
    document
}

shared void run() {
    value d = document;
    print("Done");
}

I think i figured out the bug: in function dre$$ of ceylon.language-1.3.2.js there are two nested for loop that cycle with the same variable “i” (one on line 977, the other in line 1022). Since they’re nested, javascript handle the “i” variable as the same variable (despite both having “var”) as per this answer.

The second loop is only reached for particular cases, for example while “working” (i don’t really know what the function does) on HTMLElement.dataset. In this case the second loop is smaller than the first, effectively rewinding the “i” variable to a lower value.

Workaround is simply changing the name of the smaller, inner loop, which becomes for example: for (var ii=0;ii<mm.sts.length;ii++) { if (mm.sts[ii].a && mm.sts[ii].a[_t]) { object.$$targs$$[_t]=mm.sts[ii].a[_t]; _t=mm.sts[ii].a[_t]; break; } I don’t know if the code is hand written or generated, in the second case the generator probably needs to be corrected.

I hope this helps!

I’ll close this one and open another one for the other things to check.
