Segmentation fault (core dumped)

Hello,
I was looking for a tool to cut video without re-encoding in none key-frames and found vireo.

I used this command to trim a video:
trim "23000" "14000" "1.mp4" "3.mp4"
but it gives me this output:
Segmentation fault (core dumped)
What is the problem?

Can you share the inputs you used? If you're seeing a segfault we should fix it.

While compiling vireo I got a linker error so I used this to change makefile:
sed -i 's+-llsmash+/usr/lib/liblsmash.a+g' Makefile

Then used trim like this:
trim "23000" "14000" "1.mp4" "3.mp4"
and got Segmentation fault (core dumped)

This is gdb backtrace for my input:

I tested this on two devices with ubuntu 18.04 64bit and got same error.
