You have debug symbols in sssd (frame #7,#6), but you don't have debug symbols
in library libtevent (frame #5-#2) and glibc (frame #1,#0)
It seems that either you found bug in libteven or you did not properly generate
backtrace. It is litle bit tricky to debug multi process application.
The best way, how to obtain backtrace is from core dump file.
Core file is not generated by default. You can allow it with command:
sh4.2# ulimit -c unlimited
//then you have to run sssd from the same terminal, debug level is optional in
//this case
sh4.2# sssd -i -d7
//perform action to reproduce bug (segfault)
//New file(core) should be created in current directory
//It is very likely, that core will be generated from sssd_be (I guess)
//You can check it by calling command
sh4.2# file ./core
//you can see similar output from file command
//./core: ELF 64-bit LSB core file x86-64, version 1 (SYSV), SVR4-style, from
'xterm'
^^^^^^^^
This information is important
name_of_segfaulted_process
//run gdb
sh4.2# gdb <name_of_segfaulted_proces> ./core
