We are developping a plugin for inDesign and while testing a new feature on a Mac we noticed that sometimes InDesign was crashing. We managed to reproduce this bug in a very simple indesign script that make inDesign crash 100% of the time and I'm looking for a way to get around this inDesign bug.

The crash occurs when we programatically add an htmlItem to a pageItem then close the document too quicky, It's only on Mac, doing that on windows works perfectly. The crash error seems to be a memory usage problem on inDesign's side.

Here is the script code :

var document = app.activeDocument;
var sourcePageItem = document.allPageItems[0];

sourcePageItem.htmlItems.add(
document.activeLayer,
LocationOptions.AT_END,
sourcePageItem,
{
geometricBounds: sourcePageItem.geometricBounds,
htmlContent: '<b>Hello</b>',
}
);

document.close(SaveOptions.NO);

other observations :

-Doing a sourcePageItem.htmlItems[0].remove(); to remove the htmlItem after adding it doesn't change anything, so the problem comes from using the function htmlItems.add() and not having an htmlItem in the document.
-Delaying the close by using $.sleep(5000) before fix the crash, but we can't rely on it as the delay needed increase with the number of htmlItems added and it might be different from a computer to another due to performances.
-Saving the document or not doesn't change anything


I've added the script, my clean document with just a rectangle frame and the crash report with this post.

If there is no way to fix it, do you have an idea to get around this inDesign bug ?
