Package: gdb Version: 8.1-4+b1 Severity: normal Tags: upstream Dear Maintainer,
while trying to debug #914300 I wanted to use the record feature of gdb. Unfortunately that stopped on me with an assertion failed. See at the bottom of this mail for an example run. I was able to find the issue starting between these debian packages. - gdb-minimal_7.10-1.1 works - gdb-minimal_7.11.1-1 fails This upstream bug [1] seems to handle that exact issue. There I have forwarded my findings and a git bisect result, of which commit [2] has introduced this. Kind regards, Bernhard [1] https://sourceware.org/bugzilla/show_bug.cgi?id=20456 [2] https://sourceware.org/git/gitweb.cgi?p=binutils-gdb.git;a=patch;h=398e081380a204e3b9fb4eb4da069ccf471f930e -- System Information: Debian Release: buster/sid APT prefers testing-debug APT policy: (500, 'testing-debug'), (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 4.18.0-2-amd64 (SMP w/8 CPU cores) Locale: LANG=de_DE.UTF-8, LC_CTYPE=de_DE.UTF-8 (charmap=UTF-8), LANGUAGE=de_DE.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Init: systemd (via /run/systemd/system) LSM: AppArmor: enabled Versions of packages gdb depends on: ii libbabeltrace1 1.5.6-1 ii libc6 2.27-8 ii libexpat1 2.2.6-1 ii libipt2 2.0-2 ii liblzma5 5.2.2-1.3 ii libncursesw6 6.1+20181013-1 ii libpython3.6 3.6.7-1 ii libreadline7 7.0-5 ii libtinfo6 6.1+20181013-1 ii zlib1g 1:1.2.11.dfsg-1 Versions of packages gdb recommends: ii libc6-dbg [libc-dbg] 2.27-8 Versions of packages gdb suggests: pn gdb-doc <none> pn gdbserver <none> -- no debconf information benutzer@debian:~$ gdb -q --args kalgebra Reading symbols from kalgebra...Reading symbols from /usr/lib/debug/.build-id/db/c25dd2c87a837265a5fccb742e0b65684c3166.debug...done. done.
