Description thierry bordaz 2017-03-31 16:42:20 UTC

Description of problem:

The problem is an access to an invalid offset into a structure.
Crash should be rare or even not possible, as it is an access in stack few bytes after the structure but as it is done in a called subfunction, memory is (should) always be accessible.

It does not create wrong/invalid result
 
Version-Release number of selected component (if applicable):
1.3.6

How reproducible:
Running AddressAnalyzer

No identified test case to generate crash or invalid result

Steps to Reproduce:
1. enable memberof
2. do tests with groups
3.

Actual results:
