Crashes after a while when connected via an external serial channel

[aivx]

When connecting and transmitting data via an external serial port, the program shuts down after a while with one of the errors:

• malloc(): mismatching next->prev_size (unsorted);
• malloc(): unaligned tcache chunk detected;
• malloc(): smallbin double linked list corrupted;
• malloc(): corrupted top size;
• double free or corruption (!prev);

or just a segmentation fault

Hi.
Serial Port is working for me.
How can I reproduce the issue?
Also which version are you using?

Hello.
For example, if you connect a real Arduino Uno to a computer with a downloaded program that prints Serial characters in a loop with a small delay and plug its Serial port into a virtual Arduino in SimulIDE and accept these characters, then after a while SimulIDE crashes with various errors.

And the more often the characters are sent from the real Arduino Uno to the virtual Arduino Uno, the more likely the SimulIDE will crash.

I last tested it on the last compiled working build from this repository
