Subjectfailed to add c++ probe
hi,
Thomas reported failure to add an uprobe on libstdc++.so.6 like:

[jolsa@krava perf]$ sudo ./perf probe -x /usr/lib64/libstdc++.so.6 'std::ostream::flush'
Semantic error :There is non-digit char in line number.
Error: Command Parse Error.

it does not work also if I use the mangled name like:

[jolsa@krava perf]$ sudo ./perf probe -x /usr/lib64/libstdc++.so.6 '_ZSt5flushIwSt11char_traitsIwEERSt13basic_ostreamIT_T0_ES6_'
Probe point '_ZSt5flushIwSt11char_traitsIwEERSt13basic_ostreamIT_T0_ES6_' not found.
Error: Failed to add events.

thanks,
jirka
