Double free error while updating

[bma-vandijk]

Hi,

I stumbled upon some other thing while running a LaMachine update which I think I'm not really equipped to handle.

fatal: [LAPTOP-5N7G0RHD.localdomain]: FAILED! => {

}

In Python I can still use the python-frog binding and properly parse text, but when I try to exit Python I get the following output:

double free or corruption (fasttop)
lAborted

Thanks in advance for your help.

That is a indeed a nasty issue we have seen before in rare circumstances, see proycon/python-frog#17 .

It's a bit of a mystery still what causes it, usually it doesn't occur. Can you try the suggested solution there by explicitly removing the installed python-frog prior to running lamachine-update?

Hello,

Not sure whether I understood your tips correctly but this is what I did:

I tried updating (both normal and with force=1) after
-deleting the frog.cpython-38-x86_64-linux-gnu.so file from the site-packages dir
-deleting the python-frog folder in the lama/src folder

in both cases the folders/files were replaced after updating but the updating is still aborted with the same error. It seems I can still use Frog. Yet, while working in JupyterLab I have the feeling that Frog freezes the kernel sometimes (after reboot it usually works again) and that it may have to do something with this error.

Thanks in advance
