Description of problem:
I'm testing the following script:
====================================
# cat mod.stp
probe module("ext3").function("*") {
  printf("%s\\n",probefunc())
}
====================================

Runnning this script writes names of functions correctly as expected, but when you try to terminate it with ctrl+C, the kernel crashes (probably). When I tested it, my sessions hang and I was unable to log in with another ssh session. After some time the boxes were awaken again, rebooted. Nothing unusual was in /var/log/messages. It may possibly be a kernel bug, stap bug, or both.

Version-Release number of selected component (if applicable):
systemtap-0.7.2-2
kernel-2.6.18-92

How reproducible:
always


Steps to Reproduce:
1. create mod.stp as above
2. stap -V mod.stp
3. after a while, hit ctrl+C

Actual results:
hang

Expected results:
correct termination

Additional info:
This doesn't occur on 2.6.18-124 kernel.
