Line number of error message seems to be different than what I get
when I comment out "stable_secret" in proc01.c. I would expect you
hit error on line 393, but data from you show 392.

What is the LTP version you are running?
Has the file been locally modified? If so, please attach modified version.


I tried same glibc version as you have, but it works just fine here:

# rpm -qa glibc
glibc-2.17-68.sa1.4.aarch64
