Problem with libgnutls on bookworm running inside parallels on imac - illegal instruction

[Gunnar Stahl]

Hello Andreas, hello list,
you people are really amazing!

After an apt update / apt upgrade I saw that a new version of gnutls had been released. And the problem had disappeared, meaning my the commands which initially threw the illegal instruction now work.

On another virtual machine which I hadn’t updated yet and which therefor still had this error I tried the GNUTLS_CPUID_OVERRIDE=0x1, which resulted in the problem disappearing too. Unsetting that switch resulted in the problem being back again.

I tried all the other switches available and each resulted in the problem no longer being there. So this switch turns off the code that threw the initial error.

Anyways, after updating this system the error is gone too.

So in the end, I am truly amazed by how good you guys are. I surely don’t know if the fix for that problem was intentional or just a byproduct, but anyways, thank you!

Yt, Gunnar
