VHDL Parser Access Violation on 64-bit decimal literals

I have a VHDL-2008 file with the following line:

constant TxFreqHz : std_logic_vector(63 downto 0) := 64d"3200000000"; -- 3.2 GHz

This results in the following crash:

By changing the base to hexadecimal, everything is happy again:

constant TxFreqHz : std_logic_vector(63 downto 0) := 64x"BEBC2000"; -- 3.2 GHz

Please could you fix the bug in your compiler?

Thanks,

    Hi Bryn,


    Seem to me like a bug in the compiler. Can you pass a small design that replicate the issue?

    I can forward this to the developer to take a look.

      Good day,

      My apologies -- for some reason only the moderator reply got through to me as an email.

      Anyway -- attached is a minimal example that generates the access violation.

      Regards,

      John-Philip
