Broken bytecode when using preincrement expression via accessor

Issue #277 resolved
Jesper Öqvist created an issue

ExtendJ 8.1.0-27-gcd7effa Java SE 5

The following test generates bad bytecode:

public class Test {
  public static void main(String[] args) {
    Loop loop = new Test().new Loop();

  private int count = 1;

  class Loop {
    public int run(int num) {
      int sum = 0;
      while (count < num) {
        sum += count * count;
      return sum;

Expected result: should print 328350.

Actual result: fails to run due to a verification error:

    [junit] [FAIL] runTest[run/while_04](tests.extendj.TestJava7)
    [junit] Error output files differ expected:<[]> but was:<[Exception in thread "main" java.lang.VerifyError: (class: Test$Loop, method: run signature: (I)I) Inconsistent stack height 1 != 0
    [junit]     at Test.main(]>
