memleak.py no result with jemalloc5.3.0

[xpbob]

hi memleak.py can produce results using the jemalloc5.2 program, while the jemalloc5.3 program has no results

env: Reproduced as follows:

export LD_PRELOAD="/usr/local/lib/libjemalloc.so"
./leak_test

./memleak.py -p $(pgrep leak_test) -O /usr/local/lib/libjemalloc.so.2 

We found that it was the implementation of jemalloc that led to the changes in uprobe

Should we consider adding a custom uprobe parameter to support this scenario

Hi, I'd like to take a look at this issue. I believe I have a fix in mind. Is it okay for me to work on this?
