I'm using binutils-2.29.1-r1. When I'm trying to analyse C and C++ programs, gmon.out is generated successfully, but gprof fails to profile it. gprof only prints an empty profile containing only introduction to indexes like 'time', 'cumulative seconds', 'self seconds' ...... etc. I've tried to use gprof on different programs, some are C and some are C++, but gprof worked on none of them. Here's the output of uname -a: Linux PSE-Gentoo 4.12.12-gentoo #1 SMP Sun Dec 3 14:27:46 CST 2017 x86_64 Intel(R) Core(TM) i5-3470 CPU @ 3.20GHz GenuineIntel GNU/Linux

Created attachment 508212 [details, diff] E.in and E.out is the testdata used to generate gmon.out, gprof.out is what gprof printed.
Does it still happen? Can you provide exact commands you ran? I'm very new to gprof.

I've updated to new versions of binutils before 1 year, and the problem disappeared. I don't know if the problem still exists on 2.29.1-r1, but it has already been masked.
