mysqld down after update through custombuild

After an update of mysqld through custombuild, I can't start mysqld...

I tried to build it again and got the following error:

When trying to start mysqld in safe mode, I got the following error:

Do you have any suggestions?

Thanks in advance!

Problem is fixed for now by a build all.

I don't know what the exact problem was, but I'm happy all websites are online again.

Kind regards
Christophe
