Description Steve Conklin 2007-10-10 14:05:30 EDT
Description of problem:

Invoking semodule with the -B option and an extra argument causes the process to
hang and consume CPU.

Version-Release number of selected component (if applicable):


How reproducible:

From a root shell, execute 'semodule -B aaa'

Steps to Reproduce:
1. execute 'semodule -B aaa'
2. Note that it does not complete, and that it is comsuming 100% CPU. Also,
no response to a SIGINT (^C) from the terminal.
3. Kill it using kill -9
Actual results:

semodule never completes and returns an error.

Expected results:

semodule should complete and possibly return an error

Additional info:

I tried this on a rawhide system, X86_64 running policycoreutils 2.0.29-1.fc8,
and it segfaults.
