Description Ricardo I. Vieitez 2010-08-04 12:57:48 UTC
Description of problem:
There are compilation warnings that are a sign of potential application bugs. They should be corrected in future releases.

Version-Release number of selected component (if applicable): 2.02.70. Older versions affected, too.



How reproducible:
Always


Steps to Reproduce:
1. Compile the source code.
  
Actual results:
Warnings are displayed.

Expected results:
There should be no warning. Dereferencing if needed should be done with an explicit cast.

Additional info:

 * QA Notice: Package has poor programming practices which may compile fine but exhibit random runtime failures.
 * device/device.c:81: warning: dereferencing pointer ‘part’ does break strict-aliasing rules
 * device/device.c:81: warning: dereferencing pointer ‘part’ does break strict-aliasing rules
