It gives an odd error (see attached). Is that a bug in eu-stack?
However if I'm understanding the output correctly then it does
indicate that the addresses are located in the pre-upgraded glibc.

Also attached.
Note that I have these debuginfo packages installed:
$ rpm -qa | grep glibc.*debug
glibc-debuginfo-2.27.9000-35.fc29.x86_64
glibc-debuginfo-common-2.27.9000-35.fc29.x86_64
However there is no debugsource for glibc. Is that right?
