--- Comment #12 from vincenzo Innocente <vincenzo.innocente at cern dot ch> ---
confirm that the patch solves the issue

c++ -std=c++23 testStacktrace.cpp -lstdc++exp -g -DINLIB -fpic -shared -o
liba.so -ldl;c++ -std=c++23 testStacktrace.cpp -lstdc++exp -g -DINMAIN -L. -la
-Wl,-rpath=.; ./a.out
   0# nested_func2(int) at
/data/user/innocent/MallocProfiler/tests/testStacktrace.cpp:63
   1# nested_func(int) at
/data/user/innocent/MallocProfiler/tests/testStacktrace.cpp:93
   2# func(int) at
/data/user/innocent/MallocProfiler/tests/testStacktrace.cpp:101
   3# main at /data/user/innocent/MallocProfiler/tests/testStacktrace.cpp:106
   4# __libc_start_main at :0
   5# _start at :0
   6#

what is the last empty entry is a different story I suppose (not an issue at
the moment).

Thanks again for the fast action
