Issue

The output below are the details that reproduce my problem. Note that I am following the instructions generated by

macos-show-caveats.sh

I tried removing gdb and its codesign (using conda and the Keychain Access progam), but the problem just repeated itself.

I tried exiting gdb and re-running it many times and got the same result.

Hi,

You are on a M1 Mac. GDB does not support this platform. I'm guessing you it (or your whole conda installation) is an x86-64 version and is running in Rosetta ?

Either case, I don't think this use case can work.

You'll have better luck with LLDB for debugging on that platform.

Cheers!
