Hi,

Strict

Function Main:Int()
    Local empty:Int[] = [].Resize(5)
    Print "Empty  Resize Lenght: " + empty.Length()

    Local filled:Int[] = [0].Resize(5)
    Print "Filled Resize Lenght: " + filled.Length()

    Return 0
End

leads to

** BUILD SUCCEEDED **

Empty  Resize Lenght: 0
Filled Resize Lenght: 5

which seems to be a bug :/

Hi,

i've wrote some tests to make this case a little bit more specific. The code can be found here and to reproduce this, just compile & run the runall.monkey file.

Running debug cpp/glfw tests on macos:

  bugs.resizeemptyarraytest.ResizeEmptyArrayTest
    TestResizeWithItems 
    TestResizeEmptyAfterAssignment 
    TestResizeEmptyDirect [FAILED]

There was 1 failure:

1) ResizeEmptyArrayTest.TestResizeEmptyDirect in bugs/resizeemptyarraytest.monkey
  Failed asserting that two integers are equal
  Expected: 1
  Actual  : 0

FAILURES!
Tests: 3, Failed: 1, Skipped: 0, Incomplete: 0.

All the best,
Michael

PS: The used testing framework is part of bono and can be found here.

Nice bug!

[].Resize() shouldn't actually compile in the first place (what type would the elements have?!?) - will fix.
