Hi, I found a potential null pointer dereference bug in the project source code, and I have shown the execution sequence of the program that may generate the bug on the graph below. The red text illustrates the steps that generate the bug, the file path can be seen in the blue framed section.
Although the code shown is for version 10.3 but is still exist in current version
would you can help to check if this bug is true?thank you for your effort and patience!

Bug
Major
The bug may or may not be exist, but it's impossible to tell from the analysis.
The analysis is invalid, because ha_federatedx.cc is never linked with libmariadb.
