Apologies that I missed that question.

In Debian stable (Trixie), glibc 2.41-12+deb13u1, this error is no
longer present.

I can run all commands of sprof(1), however none produces any content,
i.e. something beyond the header lines. As I'm not a programmer, I
don't know if this is something to worry about.

helge@twentytwo:/tmp$ sprof -p libdemo.so.1 $LD_PROFILE_OUTPUT/libdemo.so.1.profile
Flat profile:

Each sample counts as 0,01 seconds.
  %   cumulative   self              self     total
 time   seconds   seconds    calls  us/call  us/call  name

And no, I don't expect any of the output to be translated, I was just 
curious to try this out.

If you need any further input from my side, please let me know,
otherwise I'm fine as well.

Greetings

        Helge
