Armv7 aarch64 'Segmentation fault'

[ghost]

I compiled and executed successfully MegaFuse on my amd64 machine, but when I use it on any arm machine, f.e: my NanoPi NEO2 or my Khadas Vin Pro, I get a runtime error.

I "played" a little with gdb to get more info:

So i wanted to know if this can be fixed adding or removing any gcc flag or something similar...
