Short description of error
When I add some bevel depth to a text object, blender crashes. This is the error from the terminal:

Blender(6343,0x700003ec2000) malloc: Incorrect checksum for freed object 0x7f808c457090: probably modified after being freed.
Corrupt value: 0x3c9bd233bbca8474
Blender(6343,0x700003ec2000) malloc: set a breakpoint in malloc_error_break to debugExact steps for others to reproduce the error*
With the default blender scene: delete cube. Add text object. In data properties -> geometry -> bevel depth, click on the right arrow a few times to increase the value. Blender crashes, sometimes after clicking once, sometimes after a few times.

While slowly clicking the arrows to increase and decrease the value, it took approximately 30-40 clicks before it would crash. Dragging the value it crashed almost instantly.
Running with --debug --debug-cycles --debug-all --factory-startup it crashes on the first click.
