Hi, Lluís -
> I've attached both. BTW, I'm using debian's gcc 6.1.1-1. Thank you. Those both look just fine, argh. Could you try using gdb's "static probe points" facility to break at the same point, to see if the arguments are accessible? https://sourceware.org/gdb/onlinedocs/gdb/Static-Probe-Points.html Maybe provide a disassembly of the two functions of that binary, just to confirm that the numeric parameters are being passed? - FChE
