Bug ID: 22549
Summary: Gprof prints an empty profile including no data
Product: binutils
Version: 2.29
Status: UNCONFIRMED
Severity: critical
Priority: P2
Component: gprof
Assignee: unassigned at sourceware dot org
Reporter: PhoenixStarEclipse at gmail dot com
Target Milestone: ---
I'm using binutils-2.29.1-r1 on Gentoo Linux.
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

E is the executable file compiled with g++ -pg -o E E.cpp, gprof.out is the
output of gprof, E.in and E.out are valid input and output of E and are used to
generate gmon.out.
