Short description of error
Blender crash after making new file by: File > New > any option. This happens after using Grease Pencil.
Error in terminal:
Floating point exception (core dumped)
Exact steps for others to reproduce the error
@Clément Foucault (fclem) The problem is when free the memory gpu_viewport_storage_free() when free the grease pencil object memory.
The unique change I did was to add the render of gp objects for selection.
Could you take a look of what is happenning, I don't know how works this area of the GPU and Draw manager.
I assign the task to @Clément Foucault (fclem), and later if something in grease pencil area need to be changed we can reasign to me.
To give more details, this is an extract of the callback:

The error is gpu_viewport_engines_data_free() before line MEM_freeN(data->fbl);
After doing some debug,the steps to reproduce are:
