[p96114175]

When I attempt to run the demo-fbdev binary on my Raspberry Pi, the program crashes with a double free or corruption (fasttop) error. Below is the output from the terminal:

$ sudo ./demo-fbdev 
22:21:32 INFO  backend/fbdev.c:199: Environment variable $FRAMEBUFFER not set, use /dev/fb0 by default
double free or corruption (fasttop)
Aborted

Steps to Reproduce

Step 1: Run the command:

make clean config

Step 2: Navigate to Demo Applications.

Step 3: Enable the Build spline demo option and save the configuration.

Step 4: Run the following command:

sudo ./demo-fbdev

Step 5: Follow the mouse movement shown in the linked video by continuously moving the mouse to the far left, right, or front. This will reproduce the issue.
