--- Comment #1 from William Cohen <wcohen at redhat dot com> ---
As the upstream systemtap doesn't currently build on RHEL7 because of missing
debuginfod support in elfutils resorted to trying things with the existing
systemtap available in RHEL7.9.  Things appeared to work correctly:

[root@hpe-dl160gen8-01 ~]# rpm -q kernel glibc systemtap
kernel-3.10.0-1160.el7.x86_64
glibc-2.17-317.el7.x86_64
glibc-2.17-317.el7.i686
systemtap-4.0-13.el7.x86_64
[root@hpe-dl160gen8-01 ~]# stap dbg-core.stp -c /usr/bin/ls
anaconda-ks.cfg  NETBOOT_METHOD.TXT  rpmbuild
dbg-core.stp     original-ks.cfg     systemtap-5.0-1.el8.src.rpm
dbg-core.stp~    RECIPE.TXT          systemtap_write
call _IO_new_fclose()call _IO_new_fclose()[root@hpe-dl160gen8-01 ~]# cat
dbg-core.stp
probe process("/lib64/libc.so.6").function("_IO_new_fclose").return
{
  printf ("call _IO_new_fclose()")
}


The only difference I can see is that this is the kernel is a bit newer. 
Doesn't look like we are able to replicate this.
