=== If no file names and line numbers are shown below, one can run addr2line -Cpfie my_exefile my_line_address to convert `my_line_address` (e.g., 0x4a6b) into file name and line number. Or one can use amrex/Tools/Backtrace/parse_bt.py. === Please note that the line number reported by addr2line may not be accurate. One can use readelf -wl my_exefile | grep my_line_address' to find out the offset for that line. 0: ./Castro2d.gnu.TEST.TPROF.MPI.OMP.SMPLSDC.ex() [0x67b246] amrex::BLBackTrace::print_backtrace_info(_IO_FILE*) /raid/testing/castro-gfortran/amrex//Src/Base/AMReX_BLBackTrace.cpp:179:39 1: ./Castro2d.gnu.TEST.TPROF.MPI.OMP.SMPLSDC.ex() [0x67de09] amrex::BLBackTrace::handler(int) /raid/testing/castro-gfortran/amrex//Src/Base/AMReX_BLBackTrace.cpp:85:15 2: ./Castro2d.gnu.TEST.TPROF.MPI.OMP.SMPLSDC.ex() [0x576737] amrex::Error_host(char const*) /raid/testing/castro-gfortran/amrex//Src/Base/AMReX.cpp:217:1 3: ./Castro2d.gnu.TEST.TPROF.MPI.OMP.SMPLSDC.ex() [0x45b821] Castro::read_params() /raid/testing/castro-gfortran/Castro//Source/driver/Castro.cpp:364:5 4: ./Castro2d.gnu.TEST.TPROF.MPI.OMP.SMPLSDC.ex() [0x48a17c] Castro::variableSetUp() /raid/testing/castro-gfortran/Castro//Source/driver/Castro_setup.cpp:209:23 5: ./Castro2d.gnu.TEST.TPROF.MPI.OMP.SMPLSDC.ex() [0x6f590c] amrex::Amr::InitAmr() /raid/testing/castro-gfortran/amrex//Src/Amr/AMReX_Amr.cpp:239:28 6: ./Castro2d.gnu.TEST.TPROF.MPI.OMP.SMPLSDC.ex() [0x6f786c] amrex::Amr::Amr(amrex::LevelBld*) /raid/testing/castro-gfortran/amrex//Src/Amr/AMReX_Amr.cpp:212:1 7: ./Castro2d.gnu.TEST.TPROF.MPI.OMP.SMPLSDC.ex() [0x430096] main /raid/testing/castro-gfortran/Castro//Source/driver/main.cpp:147:17 8: /lib64/libc.so.6(+0x40440) [0x7f054ec40440] __libc_start_call_main /usr/src/debug/glibc-2.34-38.fc35.x86_64/csu/../sysdeps/nptl/libc_start_call_main.h:58:16 9: /lib64/libc.so.6(__libc_start_main+0x80) [0x7f054ec404f0] call_init inlined at /usr/src/debug/glibc-2.34-38.fc35.x86_64/csu/../csu/libc-start.c:376:5 in __libc_start_main@@GLIBC_2.34 /usr/src/debug/glibc-2.34-38.fc35.x86_64/csu/../csu/libc-start.c:128:20 __libc_start_main_impl /usr/src/debug/glibc-2.34-38.fc35.x86_64/csu/../csu/libc-start.c:376:5 10: ./Castro2d.gnu.TEST.TPROF.MPI.OMP.SMPLSDC.ex() [0x452535] _start at ??:? ===== TinyProfilers ====== main() Amr::InitAmr()
