>Description:
GCJ complains while compiling the finalization method of
a class when I believe it shouldn't.
// Take from http://www-cse.ucsd.edu/users/wgg/JavaProf/Code/benchmark.tar.gz
class GCTest {
  static int objs_collected = 0;
  static final int GC_POINTERS = 200;
  static final int GC_OBJECTS = 2000;
  static final int size = 4725;
  public void start() {
    for(int i = 0; i < GC_OBJECTS; i++) {
      GCTestElem objects = new GCTestElem(size);
    }
  }
}
class GCTestElem {
  byte collect[];
  public GCTestElem(int size) {
    collect = new byte[size];
  }
  protected void finalize() {
    GCTest.objs_collected++;
  }
}
>How-To-Repeat:
Copy code to GCTest.java
compile: gcj GCTest.java to get

GCTest.java: In class `GCTestElem':
GCTest.java: In method `finalize()':
GCTest.java:21: Invalid argument to `++'.
    GCTest.objs_collected++;
                         ^
