bird3 3.0.1 produces invalid opcodes on amd64

[jmarcet]

I need to revert 9935dfd to have a working bird3 on master amd64.

Version 3.0.1 fails due to invalid opcodes:

@jmarcet Please report that to the bird mailinglist:

I think the issue here is that recent PRs for bird are not tested on the real device and it counts only on CI here.

[BKPepe]

I've looked at it further. Version 3.0.1 is no longer in the master branch as there is version 3.1.0 already.
However, we do have 3.0.1 in the stable version (OpenWrt 24.10), even though there is already version 3.0.3. @jmarcet would you be so kind to test the 3.0.3 to verify if your issue is fixed, please?

[jmarcet]

At the moment I'm reverting 3.10 and 3.0.1 since both fail. I have not tried 3.0.3. Shall I try it?

[BKPepe]

Please do.

[jmarcet]

I cannot find version 3.0.3:

[BKPepe]

Hmm, but it is released based on this email:

I'm afraid 3.0.3 also fails:

❯ dmesg | grep bird

Please test with the new 3.2.0 package

[jmarcet]

I still have to stick to version 3.0.0, current version in the tree, 3.3.1, still causes the same invalid opcode errors.

[BKPepe]

In this case, I would suggest to reaching Bird developers for help and provide them as much details as you could to investigate this further.
