    When I try to launch the editor It says "Illegal instruction", I'm using the self extracting package.

    Anyone else have the same message?

    Are you sure you are running on amd64 architecture?

    Same issue here with Debian Stretch 64bits (I'm sure :) )
    Version 5.6.0xb3 was working fine except the few known bugs.
    It might be useful to know that I use a quite old CPU : Core2Duo E6750

    Sometimes updating the microcode can fix this.

    I will wait to update until I see the results of this. Thanks for the great work Tak, the Linux builds are coming fast and hard.

    Hi Tak,
    It seems the crash does not generate a core dump file, I don' know why...
    I compiled a test program with a segmentation fault, and got the core dump so I'm sure my terminal is set up correctly.

    If you have any suggestions, I will try them. If not, I hope Hoogin has more luck.

    Here is my core dump. Core dump link.
    I'm running an older cpu on this machine, AMD Phenom II x4 955.

    Ok, it looks like one of our middleware libraries was built to use sse4.1 - we'll address that.

    Please build it without sse4.1 requirement, I have Q6600 and it supports only sse3 :(

    Nothing has changed in this area - we're still working on getting new builds of the affected code.

    I have the same problems with 5.6.x. I'm tried 5.5.1xf1 and it works. Had not much time to look into it so can't say anything other than it starts =)

    I removed 5.6 and re-installed 5.5.1f1 and it worked for me.

    Yes I have already tried it but nothing changed. And last version 5.6.0b10 did not help me.
    May I help you to collect logs? I'll be glad to help you
