The error is obviously a segmentation fault (sudo is not necessary). Could you try running it with a debugger to tell me were the fault happens? a backtrace would be great

I hope this is what you need

Matteo De Carlo · Answer 3 · Fri Oct 14 2022 16:48:50 GMT+0800 (China Standard Time)

no, this is just the compilation output.
I need you to run pipecontrol that you just compiled (I think you probably compiled with debug enabled)
with a debugger. There are several graphical debuggers, but the terminal can also be used like this:

$ gdb path/to/pipecontrol
(gdb) start
(gdb) continue
[... crash happens..]
(gdb) backtrace

The last command will print the location where the invalid memory access happened
