Package: valgrind Version: 1:3.11.0-1 Severity: important When I run valgrind against anything, I see warnings like this:
$ valgrind -q /bin/echo --14923-- WARNING: Serious error when reading debug info --14923-- When reading debug info from /lib/x86_64-linux-gnu/ld-2.21.so: --14923-- Ignoring non-Dwarf2/3/4 block in .debug_info --14923-- WARNING: Serious error when reading debug info --14923-- When reading debug info from /lib/x86_64-linux-gnu/ld-2.21.so: --14923-- Last block truncated in .debug_info; ignoring --14923-- WARNING: Serious error when reading debug info --14923-- When reading debug info from /lib/x86_64-linux-gnu/ld-2.21.so: --14923-- parse_CU_Header: is neither DWARF2 nor DWARF3 nor DWARF4 --14923-- WARNING: Serious error when reading debug info --14923-- When reading debug info from /lib/x86_64-linux-gnu/libc-2.21.so: --14923-- Ignoring non-Dwarf2/3/4 block in .debug_info --14923-- WARNING: Serious error when reading debug info --14923-- When reading debug info from /lib/x86_64-linux-gnu/libc-2.21.so: --14923-- Last block truncated in .debug_info; ignoring --14923-- WARNING: Serious error when reading debug info --14923-- When reading debug info from /lib/x86_64-linux-gnu/libc-2.21.so: --14923-- parse_CU_Header: is neither DWARF2 nor DWARF3 nor DWARF4 This might not actually be a valgrind bug... $ dwarfdump -i /usr/lib/debug/.build-id/1c/3104f034cf1caf07cdc1c4a5f342610146ebe5.debug .debug_info dwarfdump ERROR: attempting to print .debug_info: DW_DLE_CU_LENGTH_ERROR (47) (47) attempting to continue. $ dpkg -S /usr/lib/debug/.build-id/1c/3104f034cf1caf07cdc1c4a5f342610146ebe5.debug libc6-dbg:amd64: /usr/lib/debug/.build-id/1c/3104f034cf1caf07cdc1c4a5f342610146ebe5.debug So it might be a libc6 bug. However, I'm only seeing it causes problems in valgrind so, I guess, this seems a good place to start... :-) Thanks... peace & happiness, martin -- System Information: Debian Release: stretch/sid APT prefers testing APT policy: (990, 'testing'), (500, 'stable-updates'), (500, 'stable'), (300, 'unstable') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.3.0-1-amd64 (SMP w/4 CPU cores) Locale: LANG=en_AU.UTF-8, LC_CTYPE=en_AU.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) Versions of packages valgrind depends on: ii libc6 2.21-6 ii libc6-dbg 2.21-6 Versions of packages valgrind recommends: ii gdb 7.10-1 pn valgrind-dbg <none> Versions of packages valgrind suggests: pn alleyoop <none> pn kcachegrind <none> pn valgrind-mpi <none> pn valkyrie <none> -- no debconf information peace & happiness, martin
