=== 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: /raid/testing/maestroex-gfortran/amrex/Tools/Plotfile//fcompare.gnu.ex() [0x4f7116] amrex::BLBackTrace::print_backtrace_info(_IO_FILE*) /raid/testing/maestroex-gfortran/amrex//Src/Base/AMReX_BLBackTrace.cpp:174:39 1: /raid/testing/maestroex-gfortran/amrex/Tools/Plotfile//fcompare.gnu.ex() [0x4f8d18] amrex::BLBackTrace::handler(int) /raid/testing/maestroex-gfortran/amrex//Src/Base/AMReX_BLBackTrace.cpp:80:8 2: /raid/testing/maestroex-gfortran/amrex/Tools/Plotfile//fcompare.gnu.ex() [0x474fe1] amrex::IndexType::IndexType(amrex::IntVect const&) inlined at /raid/testing/maestroex-gfortran/amrex//Src/Base/AMReX_Box.H:78:20 in amrex::operator>>(std::istream&, amrex::Box&) /raid/testing/maestroex-gfortran/amrex//Src/Base/AMReX_IndexType.H:35:17 amrex::Box::Box(amrex::IntVect const&, amrex::IntVect const&, amrex::IntVect const&) /raid/testing/maestroex-gfortran/amrex//Src/Base/AMReX_Box.H:78:20 amrex::operator>>(std::istream&, amrex::Box&) /raid/testing/maestroex-gfortran/amrex//Src/Base/AMReX_Box.cpp:78:9 3: /raid/testing/maestroex-gfortran/amrex/Tools/Plotfile//fcompare.gnu.ex() [0x4f47eb] amrex::PlotFileDataImpl::PlotFileDataImpl(std::__cxx11::basic_string, std::allocator > const&) /raid/testing/maestroex-gfortran/amrex//Src/Base/AMReX_PlotFileDataImpl.cpp:51:25 4: /raid/testing/maestroex-gfortran/amrex/Tools/Plotfile//fcompare.gnu.ex() [0x412e72] amrex::PlotFileData::syncDistributionMap(amrex::PlotFileData const&) inlined at /raid/testing/maestroex-gfortran/amrex/Tools/Plotfile/fcompare.cpp:103:29 in main_main() /raid/testing/maestroex-gfortran/amrex//Src/Base/AMReX_PlotFileUtil.H:208:98 main_main() /raid/testing/maestroex-gfortran/amrex/Tools/Plotfile/fcompare.cpp:103:29 5: /raid/testing/maestroex-gfortran/amrex/Tools/Plotfile//fcompare.gnu.ex() [0x410630] main /raid/testing/maestroex-gfortran/amrex/Tools/Plotfile/fcompare.cpp:382:22 6: /lib64/libc.so.6(__libc_start_main+0xf3) [0x7ffae0d901a3] __libc_start_main ??:0 7: /raid/testing/maestroex-gfortran/amrex/Tools/Plotfile//fcompare.gnu.ex() [0x412abe] _start ??:0
