I was able to reproduce the crush, but just in case I was also able to successfully perform Boolean Intersection by applying Decimate modifier in Collapse mode with something like 0.8 reduction ratio, applying it and then performing an intersection. Probably this was not a valid solution, but it may work as a workaround.

I can reproduce the issue too.

Selecting the inner cylinder and using Intersect (Boolean) will cause a crash.

What I've noticed that for some reason there is no selection outline on the object DIMA.
Also in my case, adding a Decimate modifier and trying to move the slider from 1.0 down will also crash Blender.
Exporting to obj and importing it again didn't solve the issue.

for me doesn't work, blender still crash

Sorry, 0.8 decimation rate indeed doesn't work, however 0.7 and lower worked in my case. Try decreasing decimation rate to 0.7 or less, maybe it will work for you as well that way. By the way, I'm testing this on the latest build 6fbe6eb0 so maybe that is important as well.
