GDB is Unable to find libthread_db

[Attila Lendvai]

dear Guixers,

i'm trying to debug:


https://issues.guix.gnu.org/58191


which is essentally that gpaste sigsegv's:


$ gpaste-client --version
(/home/alendvai/.guix-home/profile/bin/gpaste-client:6955): GPaste-CRITICAL **: 
21:23:48.100: Error calling StartServiceByName for org.gnome.GPaste: Process 
org.gnome.GPaste received signal 11


but the error happens in a thread, and GDB is unable to find 'libthread_db 
matching inferior's thread library':



$ gdb --args ./src/client/gpaste-client --version
GNU gdb (GDB) 12.1

the same question was asked on guix-help 
(https://lists.gnu.org/archive/html/help-guix/2022-09/msg00003.html) but 
without any answers.

any hints on how to proceed?

my primary goal is to fix gpaste, which a tool that i use(d) daily. getting at 
least a backtrace from GDB to see where the error originates from would 
probably give me some hints.
