Subject: Bug: "perf record" reporting buffer overflow when writing data

Hi all,

[1.] One line summary of the problem: "perf record" reporting buffer overflow when writing data
[2.] Full description of the problem/report:
I was using perf to monitor the performance of a node server, and when I stopped the server, perf crashed while writing the data with a message of

> [ perf record: Woken up 96 times to write data ]
> *** buffer overflow detected ***: terminated

I downloaded perf version 5.10.158 (the same version that caused the issue) and compiled with debug symbols, but did not run into issues. However, after I started adding libraries to enable additional features, the buffer overflow began again.
Below is the stack trace from where the crash occurred:

Strangely, the buffer overflow crash only happens when I am also loading an additional addon to my node server that loads additional shared libraries (Basler and opencv). The matrix below summarizes:

                                         With additional node add-on   Without additional node add-on
With base features      Works                                          Works
Without base features   Crashes                                    Works

I don't know exactly which features are causing the crash, and before I manually try every permutation of features to narrow down what caused the issue, I wanted to reach out and see if you all had any thoughts.
