Crash File Empty

[Savitar407]

Hello. I am unclear as to if this is an issue or this is an input, i generated a 2 byte heap buffer overflow on my target application as described by address sanitizer but when i cat the crash file to view the input the file is empty. I assumed this was because the file was filled with spaces or some other non printable input so i ran hexdump on the file and nothing was outputted. I am running the application on kali linux. Any help would be great.

thanks
