Undefined return values of message statements

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Compile core-plot using GCC 4.2
2. CPTextLayer.m contains a statement
-(void) renderAsVectorInContext:(CGContextRef)context
{
...
CGSize shadowOffset = myShadow.shadow; // return value is undefined if myShadow 
is nil (GCC 4.2)
...
}

What is the expected output? What do you see instead?
shadowOffset should be filled with zeroes if myShadow is nil but it contains 
random - undefined - values.

What version of the product are you using? On what operating system?
core-plot 0.4 head iOS 4.3.x GCC 4.2

Please provide any additional information below.

Similar statements can be found at other locations in the library. All these 
statements return undefined values.

The above and the directly following statement and all similar statements in 
core-plot should be replaced with

  if (myShadow == nil)
  {
    shadowOffset.height = 0.0f;
    shadowOffset.width  = 0.0f;
    shadowRadius        = 0.0f;
  }
  else
  {
    shadowOffset = myShadow.shadowOffset;
    shadowRadius = myShadow.shadowBlurRadius;
  }
