Re: [Valgrind-developers] Regarding the valgrind error

[Reddy K <har...@gm...>]

Hi Paul,

Thank you very much for helping me.

Sorry for the late reply. I thought of sharing the result of
--trace-childern=yes but it has not crashed yet.  So I will share those
results once I get the crash report.

Please find the details below.
which Valgrind version : *valgrind-3.15.0-3.6.1.x86_64*

which operating system : *"SUSE Linux Enterprise Server 12 SP5"*

which compiler : *Linux version 4.12.14-122.103-default (geeko@buildhost)
(gcc version 4.8.5 (SUSE Linux) ) #1 SMP Tue Nov 23 14:22:07 UTC 2021
(d263070*)



earlier  I was running the command like below and now I have added
--trace-children=yes and will let you know the results.

valgrind --tool=memcheck --num-callers=128
--log-file=./valgrind_2022may27_0128_bst.txt --error-limit=no --leak
-check=full --show-reachable=yes /opt/novell/xad/sbin/start-xad-krb5kdc


Thanks & Regards
Haritha
