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

And this is the code caused it, look around 'ribbon' object:
module VGA_HighEnd ( clk, rst,
iX_video, iY_video,
oR_video, oG_video, oB_video,
tumblers, endFrame, dbg_val );
parameter RES_X_H= 1240;
parameter RES_Y_H= 1024;
parameter XY_STEP_H= 7;
parameter RES_X_L= 640;
parameter RES_Y_L= 480;
parameter XY_STEP_L= 8;
input clk;
input rst;
input signed iX_video;
input signed iY_video;
output reg oR_video;
output reg oG_video;
output reg oB_video;
input tumblers;
input endFrame;
output wire dbg_val;
wire V_out2;
wire high_res= 1;
reg count;
wire signed x;
wire signed y;
assign x= (iX_video- (high_res ? RES_X_H/2 :RES_X_L/2 ));
assign y= (iY_video- (high_res ? RES_Y_H/2 :RES_Y_L/2 ));
//reg ribbon;// NO CRASH
always@(posedge clk or posedge rst)
begin
if ( rst )
begin
count= 0;
end
else
begin
if ( endFrame )
begin
count<= count +1;
ribbon <=count;
end
// Y'UV ->RGB
oR_video= {7{ribbon}};
oG_video= count;
oB_video= -1;
end
end
endmodule
reg ribbon;// CRASH !!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!
//reg ribbon;// NO CRASH

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- Mark as New

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.
