That's just not true in my case. Most of the asserts I triggered 
were after updating to a newer compiler version.

I don't find -v helpful as it only points to a single haystack 
out of many, I still have to find the needle. The backend source 
is hard to get into, it would really help to know a little bit 
more about the cause for the error.

One assert made me delay updating to a newer DMD version for like 
a year. I was reluctant to make the bug report because of the 
size of my codebase and inability to make a simple test case, I 
didn't even know for certain which function was the cause for it. 
Certainly just stating that an assert was triggered in this and 
this line of the backend is not enough?

Having more information would help create those bug reports.
