            Bug ID: 108146
           Summary: gcc -pg does not produce gmon.out
           Product: gcc
           Version: 12.2.1
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: gcov-profile
          Assignee: unassigned at gcc dot gnu.org
          Reporter: Sid.Touati at inria dot fr

  Target Milestone: ---

Created attachment 54112
  --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=54112&action=edit
source code (C and h files) + makefile. Just type make, then run a.out.

Hi,
please find enclosed my archive that contains my source files and make.
Juste type make to generate a.out, then execute a.out to see the problem.

The problem is that the file gmon.out is not generated. I checked the assembly
generated by gcc, gmon functions are inserted correctly. When I debug the
binary code, it seems that gmon functions are not called... This is a nightmare
to understand why :)

I checked that this problem does not happen with many other C applications. I
do not understand why it happens here. I checked this "bug" on two distinct
machines. 

Here is my current configuration: 
touati@:~/tmp/mypb> uname -a
Linux  6.0.12-300.fc37.x86_64 #1 SMP PREEMPT_DYNAMIC Thu Dec 8 16:58:47 UTC
2022 x86_64 x86_64 x86_64 GNU/Linux

It is a fedora 37 workstation.

Maybe it is a bug in "gcc -pg". 

Regards
S.T.

Hey, it's related to the fact the mcount in glibc enters GMON_PROF_ERROR state.
That happens in:

(gdb) bt
#0  __mcount_internal (frompc=<optimized out>, selfpc=5075099) at mcount.c:173
#1  0x0000155555407968 in mcount () at ../sysdeps/x86_64/_mcount.S:50
#2  0x00000000004d709b in updateExclu (data=0x7ffffffd3b18, res=0x7ffffffcc5c0)
at main.c:64359
#3  0x00000000004b8e25 in main (argc=1, argv=0x7fffffffd758) at main.c:54437

(gdb) p _gmonparam.state
$10 = 2

And that's why no gmon.out file is created. Please report it to glibc guys.

Hi,
this bug has been reported to the gcov-profile component [Bug
gcov-profile/108146], Martin Liška found that it is more appropriate to submit
it to glibC guys. 

could you check it please ?

He meant filing it to https://sourceware.org/bugzilla/ .

Already reported to glibc, see the two bug reports in the see also. Also a dup
of bug 99579 too.

Btw. you can try the newly added gprofng that was added to binutils recently.

it seems that gprofng has not been integrated to fedora yet
