We are writing a testsuite for an octave program. It will be very
helpful if we know for every testcase the caller tree. This tree makes
it possible to say if an error was an error induced by the tested
function directly or by another function called by the tested
function. It makes it possible to decide how important is a function
and how often a function is used.

We need this information not in general but in relation to specific

Yep, we want *this* information. A testcase for a specific tested
function triggers the execution of other functions. We need the
caller/calling tree. Here is the scheme:

testsuite -> calls a testcase
  testcase -> calls a specific function with specific arguments
(tested function)
    specific function -> calls another function if needed
  testcase -> collect the caller-tree of specific function, store test
result, caller-tree and so on...
testsuite -> repeat with a new testcase
