=== 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: ./Maestro2d.gnu.TEST.MPI.OMP.ex(+0x20b885) [0x562437326885] amrex::BLBackTrace::print_backtrace_info(_IO_FILE*) /raid/testing/maestroex-gfortran/amrex//Src/Base/AMReX_BLBackTrace.cpp:167:39 1: ./Maestro2d.gnu.TEST.MPI.OMP.ex(+0x20d726) [0x562437328726] amrex::BLBackTrace::handler(int) /raid/testing/maestroex-gfortran/amrex//Src/Base/AMReX_BLBackTrace.cpp:71:8 2: /lib64/libc.so.6(+0x3c6b0) [0x7f35f863e6b0] __restore_rt ??:0 3: ./Maestro2d.gnu.TEST.MPI.OMP.ex(+0x3cb605) [0x5624374e6605] __vode_integrator_module_MOD_vode_integrator /raid/testing/maestroex-gfortran/Microphysics//integration/VODE/vode_integrator.F90:183 4: ./Maestro2d.gnu.TEST.MPI.OMP.ex(+0x3dcf7b) [0x5624374f7f7b] __integrator_module_MOD_integrator /raid/testing/maestroex-gfortran/Microphysics//integration/integrator.F90:130 5: ./Maestro2d.gnu.TEST.MPI.OMP.ex(+0x31a055) [0x562437435055] burner_loop ../../../Source/Src_nd/burner_loop.F90:144 6: ./Maestro2d.gnu.TEST.MPI.OMP.ex(+0x114f6d) [0x56243722ff6d] Maestro::Burner(amrex::Vector > const&, amrex::Vector >&, amrex::Vector > const&, amrex::Vector >&, amrex::Vector >&, amrex::Vector > const&, double, double) [clone ._omp_fn.0] ../../../Source/MaestroReact.cpp:255:29 7: /lib64/libgomp.so.1(GOMP_parallel+0x46) [0x7f35f881b4b6] GOMP_parallel ??:0 8: ./Maestro2d.gnu.TEST.MPI.OMP.ex(+0x11710d) [0x56243723210d] amrex::iMultiFab::~iMultiFab() inlined at ../../../Source/MaestroReact.cpp:217:70 in Maestro::Burner(amrex::Vector > const&, amrex::Vector >&, amrex::Vector > const&, amrex::Vector >&, amrex::Vector >&, amrex::Vector > const&, double, double) /raid/testing/maestroex-gfortran/amrex//Src/Base/AMReX_iMultiFab.H:81:13 Maestro::Burner(amrex::Vector > const&, amrex::Vector >&, amrex::Vector > const&, amrex::Vector >&, amrex::Vector >&, amrex::Vector > const&, double, double) ../../../Source/MaestroReact.cpp:217:70 9: ./Maestro2d.gnu.TEST.MPI.OMP.ex(+0x117a44) [0x562437232a44] Maestro::React(amrex::Vector > const&, amrex::Vector >&, amrex::Vector >&, amrex::Vector >&, amrex::Vector >&, amrex::Vector > const&, double, double) ../../../Source/MaestroReact.cpp:56:30 10: ./Maestro2d.gnu.TEST.MPI.OMP.ex(+0x10cf8a) [0x562437227f8a] Maestro::PlotFileMF(int, double, double, amrex::Vector > const&, amrex::Vector > const&, amrex::Vector > const&, amrex::Vector > const&, amrex::Vector > const&, amrex::Vector >&, amrex::Vector > const&, amrex::Vector > const&, amrex::Vector > const&) ../../../Source/MaestroPlot.cpp:361:14 11: ./Maestro2d.gnu.TEST.MPI.OMP.ex(+0x1118ee) [0x56243722c8ee] Maestro::WritePlotFile(int, double, double, amrex::Vector > const&, amrex::Vector > const&, amrex::Vector > const&, amrex::Vector > const&, amrex::Vector > const&, amrex::Vector >&, amrex::Vector > const&, bool) ../../../Source/MaestroPlot.cpp:116:33 12: ./Maestro2d.gnu.TEST.MPI.OMP.ex(+0xe2cff) [0x5624371fdcff] Maestro::Init() ../../../Source/MaestroInit.cpp:33:26 13: ./Maestro2d.gnu.TEST.MPI.OMP.ex(+0x26b9c) [0x562437141b9c] main ../../../Source/main.cpp:63:17 14: /lib64/libc.so.6(__libc_start_main+0xf3) [0x7f35f86291a3] __libc_start_main ??:0 15: ./Maestro2d.gnu.TEST.MPI.OMP.ex(+0x2bdbe) [0x562437146dbe] _start ??:0
