Our application is currently built on 32-bit PowerBuilder 2019 R3, with migration to 64-bit in the distant future. We've hit some problems now and then with our application taking up to 2 GB of memory, and was wondering if any testing has been done with the /LARGEADDRESSAWARE flag that can be set on Windows executables. In our own internal testing it seemed fine, but some other developers remember hitting issues testing this years ago. 

Are you aware of any major issues/problems with using the /LARGEADDRESSAWARE flag with PowerBuilder applications? Any recommendations/advice?

The only article I can find on it relating to PB was from 12.5 in 2012: https://community.appeon.com/index.php/articles-blogs/tutorials-articles/2-powerbuilder/142-breaking-platform-limitations

Thanks!
