Bug#931900: Program crashes with message "free(): double free detected in tcache 2"

[Alex Relis]

Package: projectm-pulseaudio
Version: 2.1.0+dfsg-4+b4
Severity: grave

Dear Maintainer,

First off, I'm new to the BTS so excuse me for not doing this right.
projectm-pulseaudio crashes after a few seconds in Buster. Typing "N" to
go to the next visualization effect crashes the program instantly. Here
is a log:

user at debian:~$ projectM-pulseaudio

[PresetFactory] url is

free(): double free detected in tcache 2
Aborted

Not a programmer so I really don't know what "free(): double free
detected in tcache 2", but I can only assume that's where the problem lies.

Thank you, and have a great day/night.
