[Bug runtime/5218] New: Failed to detach staprun when it attached a running script

[mhiramat at redhat dot com]

staprun unloads a script instead of detaching from it if the staprun was
attached to the script.

You can check it as follows:
1. make a script
 $ stap -m foo -e 'probe begin{;}' -p4
2. launch it.
 $ staprun -L foo.ko
3. attach.
 $ staprun -A foo
4. send SIGQUIT
 ^4
5. check whether the script is loaded
 $ lsmod | grep foo

AFAICS, the 'initialized' global variable in stapio is not initialized 
correctly when '-A' option is given.

Thanks,
