=== 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.CUDA.ex() [0x72c986] amrex::BLBackTrace::print_backtrace_info(_IO_FILE*) /raid/testing/castro-gfortran/amrex//Src/Base/AMReX_BLBackTrace.cpp:190:35 1: ./Castro2d.gnu.TEST.TPROF.MPI.OMP.CUDA.ex() [0x72f53c] amrex::BLBackTrace::handler(int) /raid/testing/castro-gfortran/amrex//Src/Base/AMReX_BLBackTrace.cpp:96:7 2: ./Castro2d.gnu.TEST.TPROF.MPI.OMP.CUDA.ex() [0x5c565f] amrex::Abort(std::__cxx11::basic_string, std::allocator > const&) /raid/testing/castro-gfortran/amrex//Src/Base/AMReX.cpp:194:1 3: ./Castro2d.gnu.TEST.TPROF.MPI.OMP.CUDA.ex() [0x642800] amrex::Arena::allocate_system(unsigned long) /raid/testing/castro-gfortran/amrex//Src/Base/AMReX_Arena.cpp:185:438 4: ./Castro2d.gnu.TEST.TPROF.MPI.OMP.CUDA.ex() [0x64a252] amrex::CArena::alloc(unsigned long) /raid/testing/castro-gfortran/amrex//Src/Base/AMReX_CArena.cpp:63:10 5: ./Castro2d.gnu.TEST.TPROF.MPI.OMP.CUDA.ex() [0x647069] amrex::Arena::Initialize() /raid/testing/castro-gfortran/amrex//Src/Base/AMReX_Arena.cpp:298:16 6: ./Castro2d.gnu.TEST.TPROF.MPI.OMP.CUDA.ex() [0x5c652d] amrex::Initialize(int&, char**&, bool, int, std::function const&, std::ostream&, std::ostream&, void (*)(char const*)) /raid/testing/castro-gfortran/amrex//Src/Base/AMReX.cpp:508:19 7: ./Castro2d.gnu.TEST.TPROF.MPI.OMP.CUDA.ex() [0x43c6f1] main /raid/testing/castro-gfortran/Castro//Source/driver/main.cpp:78:18 8: /lib64/libc.so.6(+0x3feb0) [0x7fcbaf43feb0] __libc_start_call_main /usr/src/debug/glibc-2.34-42.fc35.x86_64/csu/../sysdeps/nptl/libc_start_call_main.h:58:16 9: /lib64/libc.so.6(__libc_start_main+0x80) [0x7fcbaf43ff60] call_init inlined at /usr/src/debug/glibc-2.34-42.fc35.x86_64/csu/../csu/libc-start.c:376:5 in __libc_start_main@@GLIBC_2.34 /usr/src/debug/glibc-2.34-42.fc35.x86_64/csu/../csu/libc-start.c:128:20 __libc_start_main_impl /usr/src/debug/glibc-2.34-42.fc35.x86_64/csu/../csu/libc-start.c:376:5 10: ./Castro2d.gnu.TEST.TPROF.MPI.OMP.CUDA.ex() [0x453205] _start at ??:? ===== TinyProfilers ======
