Hi,
Good Point. But putting symbols aside, the addresses do not match, by themselves.
Regards.

Thanks. I did both of your changes. Perhaps some outputs are revised.
But I still have repeated function calls and the script detects them.
Here is one of them when the sampling period is 1000 events:

<snip>

Here, we have two consecutive "7f91788120b5
gtk_widget_propagate_state+0x195
(/usr/lib/x86_64-linux-gnu/libgtk-3.so.0.2200.30) gtkwidget.c:0" lines,
while "gtk_widget_propagate_state+0x195" is not recursive. It should
call "gtk_container_forall", which does not occur even after the second
(inner) call.

Potentially you are just lacking some debug symbols here for this GTK library. note that "gtkwidget.c:0" is bogus already - the line numbers start with 1, so a line of 0 reported indicates a lack of (full) debug information for this
file.

Cheers
