Visualization issue using Python 3.12.4

[belliriccardo]

Hi! First of all I wanted to thanks the author for this great profiling library, I use it extensively as a quick and intuitive check of what might be taking too much time in my code.
I recently upgraded to Python 3.12.4, and by profiling the same script with two different python versions I get two very different results: the (correct) one using Python 3.11.9:

And the (erroneous) one, using Python 3.12.4 (check those crazy times!):

I've looked around to check what could cause this method 'disable' of '_lsprof.Profiler' objects issue, and it seems to indicate a misuse of the cProfile module from within Python itself; this is not the case in my script as I don't use it at all in my code, and just as an external module.
Then I looked up the changes from 3.11 to 3.12 and found PEP 669; maybe this is causing the issue? I also saw PR #195, so if this is an already known problem I'm sorry for wasting some of your time and consider this issue as a "+1" to that request 😄

So I can try to replicate this, what method are you using to invoke the profiler? python -m cProfile, or something else?

Hi @jiffyclub! Yes, I was just calling python -m cProfile -o output.prof script.py, no other particular arguments. If it can help, the program in question was a fork of nsiqcppstyle, a static code checker; it is a single threaded application. Right now I've upgraded to the latest 3.12.7 and modified the code even more, so I don't know if I can 100% reproduce the issue; however, seeming as a bunch of other people reacted to my issue, maybe others can also comment with a simpler reproducible example (since nsiqcppstyle requires an actual C/C++ repository and a bit of setup)
