crash report

Hello, my Quartus is crashed, and I have web edition so can't find any other option to report it:

//reg ribbon;//    NO CRASH

    else

    I can confirm your code does not crash Quartus on my machine.

    Commenting out the line you have would mean the code wouldn't parse correctly, which would mean the Analysis & Synthesis step wouldn't complete, causing Quatrus to stop earlier through the compilation. So, this would simply point at a later stage of the compilation causing the crash.

    You could report this to Altera's tech support. However, before you do that please re-install your software and see if that helps.

    Cheers,

    Alex

    Have you deleted the db and incrementaldb directories? these can sometimes cause crashes. If this and re-installing doesnt help, you will need to raise a support request.

    Well, compiling this file separately, not cause crash (internal error), indeed, but compiling whole project does. I've attached archived project now. I tested that it still crashes and I deleted db's.

    I would direct all this to tech support, but I can't find out, how web edition user could do it. And I have made a workaround, so my interest in this now purely theoretical.
