Possibility to catch division by zero?

Is your feature request related to a problem? Please describe.
Sometimes i accidentally write a division by zero in a loop, is there a way to get the line number of the affected code?

Describe the solution you'd like
Show line number:
Division by zero at test.vhd:123

Reproducer

library IEEE;
use     IEEE.std_logic_1164.all;

entity ent is
end entity;

architecture a of ent is
    signal result : integer;
    signal clk: std_logic := '0';
begin
    clk <= not clk after 10 ns;
    process(clk)
        variable i : natural range 0 to 127 := 0;
    begin
        if rising_edge(clk) then
            result <= 10 / i;
        end if;
    end process;

end architecture;

This is supported through backtraces which depends on your configuration. So which CPU are you using and which backend ?

[FranzForstmayr]

I use llvm backend most of the time, on a i5-6200U CPU, but on some other machines i have a mcode backend. I haven't tried backtraces yet.

[tgingold]

So I suppose you are using x86-64. Correct ?

Yeah
