=== 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: ./Castro3d.gnu.TEST.TPROF.MPI.ex() [0x5e8c76] amrex::BLBackTrace::print_backtrace_info(_IO_FILE*) /raid/testing/castro-gfortran/amrex//Src/Base/AMReX_BLBackTrace.cpp:179:39 1: ./Castro3d.gnu.TEST.TPROF.MPI.ex() [0x5eaded] amrex::BLBackTrace::handler(int) /raid/testing/castro-gfortran/amrex//Src/Base/AMReX_BLBackTrace.cpp:85:15 2: ./Castro3d.gnu.TEST.TPROF.MPI.ex() [0x44a46c] std::vector, std::allocator >, std::allocator, std::allocator > > >::~vector() inlined at /raid/testing/castro-gfortran/Castro//Source/driver/runtime_parameters.H:92:56 in validate_runparams() /usr/include/c++/10/bits/stl_vector.h:680:15 validate_runparams() /raid/testing/castro-gfortran/Castro//Source/driver/runtime_parameters.H:92:56 3: ./Castro3d.gnu.TEST.TPROF.MPI.ex() [0x444c76] Castro::variableSetUp() /raid/testing/castro-gfortran/Castro//Source/driver/Castro_setup.cpp:220:14 4: ./Castro3d.gnu.TEST.TPROF.MPI.ex() [0x65260c] amrex::Amr::InitAmr() /raid/testing/castro-gfortran/amrex//Src/Amr/AMReX_Amr.cpp:239:28 5: ./Castro3d.gnu.TEST.TPROF.MPI.ex() [0x654488] amrex::Amr::Amr(amrex::LevelBld*) /raid/testing/castro-gfortran/amrex//Src/Amr/AMReX_Amr.cpp:212:1 6: ./Castro3d.gnu.TEST.TPROF.MPI.ex() [0x420b73] main /raid/testing/castro-gfortran/Castro//Source/driver/main.cpp:120:17 7: /lib64/libc.so.6(__libc_start_main+0xf2) [0x7fd86c2091e2] __libc_start_main ??:0 8: ./Castro3d.gnu.TEST.TPROF.MPI.ex() [0x42740e] _start ??:0 ===== TinyProfilers ====== main() Amr::InitAmr()
