4.7 due to potential use of uninitialized array
Robert Schweikert created AXIS2C-1589:
-----------------------------------------
Summary: Code base does not build with gcc 4.7 due to potential use of uninitialized array
Key: AXIS2C-1589
URL: https://issues.apache.org/jira/browse/AXIS2C-1589
Project: Axis2-C
Issue Type: Bug
Affects Versions: 1.6.0
Environment: openSUSE_Factory as of 04/21/12
Reporter: Robert Schweikert
axiom/src/xpath/xpath_internals_engine.c
defines the n_nodes array, but leaves it uninitialized. Values are set in a loop but are guarded by an if block. Thus the array may be uninitialized. Later on the array is used.
In gcc 4.7 this condition is detected and when building with warnings treated as errors the build fails.
