Comment 1 William Cohen 2022-01-26 14:05:58 UTC 
This has been fixed in the upstream version of systemtap by:

commit 56c498d95c4749f15980da73b4933e7443b3f26c
Author: Jonathan Wakely <jwakely.gcc>
Date:   Tue Jan 18 15:52:18 2022 -0500

    gcc12 c++ compatibility tweak: use lambdas instead of ptr_fun<>
    
    Even while stap is a c++11 code base, such cleanups make code
    nicer to look at.
Comment 2 William Cohen 2022-01-26 15:37:21 UTC 
Attempted a respin of the systemtap git sources for rawhide,  https://koji.fedoraproject.org/koji/taskinfo?taskID=81941041 . All the architectures built except armv7hl.  A number of errors of the form:

In file included from staptree.cxx:10:
staptree.h: In member function 'next_statement::~next_statement()':
staptree.h:841:8: error: pointer used after 'operator delete(void*, unsigned int)' [-Werror=use-after-free]
  841 | struct next_statement: public statement
      |        ^~~~~~~~~~~~~~
staptree.h:841:8: note: call to 'operator delete(void*, unsigned int)' here
staptree.h: In member function 'continue_statement::~continue_statement()':
staptree.h:834:8: error: pointer used after 'operator delete(void*, unsigned int)' [-Werror=use-after-free]
  834 | struct continue_statement: public statement
      |        ^~~~~~~~~~~~~~~~~~

Given that this is arch specific, it is looking like these use-after-free warning/errors may be a problem in gcc 12 rather than systemtap.
Comment 3 William Cohen 2022-01-27 21:04:41 UTC 
Have work around in the current systemtap.spec file for 247316, so the SRPM builds for rawhide.
