Trying to assign to a long variable from an exception-throwing method/property
corrupts the value of the variable.
Example :
..
long a = 100;
try {
a = someInstance.OverrideProperty; //Exception thrown by getter
}
catch {}
Console.WriteLine(a); //prints garbage
..
In addition, the exception-throwing method/property must be an override, either
of an abstract/virtual method/property.
See attached sample code.
Reproducible: Always
Steps to Reproduce:
Run the attached program on mono 2.4.2.3 or 2.6.4 on mac os x (10.5/10.6)
Actual Results:
Attached program outputs "OhNo! value = 54692285358689880"
Expected Results:
Attached program outputs "ALL OK!"
