Narrowed down the problem to working with FC5 kernel but failing with the FC6
kernel.

Looking through the archive of test results the poll_map.stp test last ran
successfully was 

stap_testing_200611070930/obj/testsuite/systemtap.log:PASS: poll_map (1)

The source code for this is the same as the one that is currently crashing.
Attempted to use the stap translator built at that time. It crashes in the same way.

/home/wcohen/stap_testing_200611070930/install/bin/stap -v
/home/wcohen/stap_testing_200611070930/src/testsuite/systemtap.samples/poll_map.stp 

When the switch on the machine from FC5 to FC6 occurred the test stopped
working. Trying the FC5 kernel, 2.6.18-1.2200.fc5, on the machine and things
work. It appears to be an issue with the kernel.

2.6.18-1.2200.fc5 i686 kernel works, but the 2.6.18-1.2869.fc6 i686 kernel fails.
