Description H.J. Lu 2024-05-20 21:29:39 UTC 
There is no _dl_mcount_wrapper prototype in installed header files.
Comment 1 H.J. Lu 2024-05-20 21:51:19 UTC 
Should we obsolete it in glibc 2.40?
Comment 2 Florian Weimer 2024-05-21 13:22:24 UTC 
Sounds reasonable to me.
Comment 3 Sunil Pandey 2024-05-21 16:38:18 UTC
