Good morning, I have an issue that I don't understand with a compiled go binary I am developing.
I have compiled the binary correctly in my dev machine. It's working in a lot of other systems (linux i386, x86_64) except in this one [1] (sadly the prod one...) I think the problem is related to the production server, an OpenStack Nova KVM instance or something... When I try to launch my binary (compiled with `go build ... `) inside this machine I get this response: # ./UFWAnalyzer Trace/breakpoint trap (core dumped) This is the "file" of the binary # file UFWAnalyzer main: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), statically linked, stripped And this is what I got when I try to debug the core dump: # gdb UFWAnalyzer core GNU gdb (Ubuntu 7.11.1-0ubuntu1~16.5) 7.11.1 Copyright (C) 2016 Free Software Foundation, Inc.
