To reproduce the issue add a probe to the malloc function of libc
# sudo apt-get install libc6-dbg
# perf probe -x /lib/x86_64-linux-gnu/libc.so.6 malloc
Probe point 'malloc' not found.
Error: Failed to add events.
It's not possible, to check if function exists just
# perf probe -x /lib/x86_64-linux-gnu/libc.so.6 -F | grep malloc
