    I had this problem too with some versions of QuartusPro, at least 19.3, both on Linux Mint and CentOS, but could not find any answers in Jan-Feb.

    Today I found your posting and also this link: https://wikis.uni-paderborn.de/pc2doc/Noctua_FPGA_Usage,_Integration_and_Development

    which provide a possible explanation and fix.

    It is related to the linux LOCALE setting, if you use another format than US (in Europe, we use decimal comma, not point).

    By setting LC_NUMERIC= ="en_US.UTF-8", at least for the QuartusPro session, the problem disappears.

    Thank you, sadly the solution resultet in yet another error.

    I also tried to sent you an email but because it's not related to a special case it just came back. (can't be deliverd)

    Because this solution is still under test is it ok to post the new error (log) here? Or do you prefer to receive it in a different way?

    Hint (this souldn't say much): it (error) points to sin_simulation_interface.cpp, Line: 1768

    info:

    Error occures in place of the old one and behaves the same, after crash I can continue compiling using "Assembler" button and the resulting sof seems to work just fine.

    Mail:

    ...Thank you for contacting Intel Corporation. We were unable to deliver your email because the email does not appear to be related to an existing case.....

    Thanks and have a nice weekend,
