Error about intel-PCM in VMware virtual system

[Monologue-y]

Hello developers, when I build the code in a Ubuntu 18.04 virtual machine and run, there is one question troubled me for a long time.

**yang@Pluto:~$ pcm

Intel(r) Performance Counter Monitor (2024-11-05 15:03:02 +0100 ID=a83f3125)

What can I do to solve the bug?

Hi, thanks for reporting the issue. Unfortunately it is not reproducible in our VMWare environment. Would it be possible to compile pcm in debug mode (sh scripts/debug-build.sh) and then run "gdb ./pcm" and then "run", then "bt" to show the assert callstack. This should be helpful to understand what is going on.
