If it helps, I can remember fixing this bug. It took two days because
due to past mistakes I find it very difficult to convince myself that
the bug is actually in the compiler and not in my code.

So yes, it is very scary to me and would like it to be fixed.

I did not submit a bug because I could not reproduce it without
submitting the whole application. The solution was to remove the const
from the parameter list.
