--- Comment #5 from William Cohen <wcohen at redhat dot com> ---
GDB has some ability to provide backtraces that include inlined functions. 
Should see how gdb is able to get that information about source line and
function name.

Used following to find an inlined function to set a breakpoint on: 
$  stap -v -L 'process("./multiple_views").function("*").inline'


$ gdb multiple_views 
...
