Problem Text
These assertions are failing on our implemenation because the
amount of time that the parent waits for the child is hard-coded
and does not allow sufficient time for the child to fill up the
stack by recursively calling a funciton, and then exit when a
SIGSEGV is generated.
The specific code I'm referring to is:
line 197 of fsetrlimit25.c:
wait_for(pid, 10*MAX_TIME_TO_RUN);
and line 248 of fsetrlimit24.c:
if ((status = wait_for(pid, 50*MAX_TIME_TO_RUN)) == -1)
When I modify these to
wait_for(pid, 500*MAX_TIME_TO_RUN);
if ((status = wait_for(pid, 2550*MAX_TIME_TO_RUN)) == -1)
these pass on our system.
Following are the journal entries which are produced after I make
these changes. It is clear from the timestamps in the journal that
the MAX_TIME_TO_RUN hardcoded in the test suite are not sufficient
on our implementation.
We request a TSD be granted for this assertion.

We recommend this request be refused.
Each of the tests referenced above completes in 1 second on the
slowest test system we have in house (a 25MHz RISC system). The
timeouts for these tests are 100 and 500 seconds respectively.
If you look at the passing journal the submitter includes you can
see that they are requesting these timeouts be increased to more
than 2280 seconds (40 min) and 4260 seconds (70 min)
respectively.
We believe that a reasonable test environment should be able to
complete these tests in the time alloted.

This is an agreed Test Suite Deficiency.
