Package: gdb Version: 8.2.50.20190222-1 Severity: minor I'm debugging libnotmuch, which is C++ code calling glib, and see the following when attempting to examine a struct:
Breakpoint 1, _notmuch_message_file_parse (message=0x560a725d81a0) at lib/message-file.c:147 147 notmuch_status_t status = NOTMUCH_STATUS_SUCCESS; (gdb) p *message->stream $1 = {parent_object = {g_type_instance = {Python Exception <class 'gdb.error'> No type named TypeNode.: g_class = }, ref_count = 1, qdata = 0x0}, super_stream = 0x0, position = 0, bound_start = 0, bound_end = -1} (gdb) The underlying problem is actually missing debug symbols for glib (installing libglib2.0-0-dbgsym fixes it). It would be great if the error message was more helpful. -- System Information: Debian Release: buster/sid APT prefers unstable-debug APT policy: (500, 'unstable-debug'), (500, 'testing-debug'), (500, 'testing'), (1, 'experimental') Architecture: amd64 (x86_64) Foreign Architectures: i386 Kernel: Linux 4.19.0-2-amd64 (SMP w/8 CPU cores) Kernel taint flags: TAINT_OOT_MODULE, TAINT_UNSIGNED_MODULE Locale: LANG=en_CA.UTF-8, LC_CTYPE=en_CA.UTF-8 (charmap=UTF-8), LANGUAGE=en_CA:en (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 1.5.6-2 ii libc6 2.28-8 ii libexpat1 2.2.6-1 ii libipt2 2.0-2 ii liblzma5 5.2.4-1 ii libncursesw6 6.1+20181013-2 ii libpython3.7 3.7.3~rc1-1 ii libreadline7 7.0-5 ii libtinfo6 6.1+20181013-2 ii zlib1g 1:1.2.11.dfsg-1 Versions of packages gdb recommends: ii libc6-dbg [libc-dbg] 2.28-8 Versions of packages gdb suggests: pn gdb-doc <none> ii gdbserver 8.2.1-2 -- no debconf information
