Crash depending on preceding user actions

spikey

I hope you didn't give up on catching array handling mistakes that happen between the keyboard and the screen ;-) by adding some additional code checks and error messages.
But actually I am not even sure if its an array problem, because removing any "meaningless" line of code could make this work and the crash will not happen anymore.

So, I drop this as much simplified, as I was able to, so it still provokes the crash and the additional information, what to do to make it happen.

Reproduction info:

Do not do any user action in FUZE beside: starting FUZE, running the code with "+" or "F5". (I have the "coding editor" as the default loading feature)
if retyping does not work, download the test program with this ID: 5TK73V5WN8

Observations:

adding or removing lines may cause the program not to crash anymore
adding more or less print() loops, causes the program to crash earlier or later
if you go to the media library section in FUZE before running the program and load any image, or probably sound as well and show it on screen and run the code afterwards, it does not crash anymore
adding or removing comments has no effect on crashing or not
modifying the looping-number may cause the program not to crash anymore
copying the push function code right into the loop, caused the crash not to happen anymore

This is the isolated code, from my original program. Its not making sense in the case of a program, its intention is just to reproduce a crash.

array d[26]=[]
int count
loop
   clear(denim)
   ink(grey)
   frames = 20
   for j = 0 to 26 loop
      d[j]=push(d[j]), "_")
      if len(d[j]) > frames then
         d[j] = []
      endif
      for i = 0 to 15 loop
      print("123456789011234567890112345678901123456789011234567890112345678901\n")
      repeat
   repeat
   ink(yellow)
   printAt(1,1,"Docked: ", docked())
   printAt(1,2,"Loop count: ", count)
   textSize(20)
   printAt(1,4,"First run after starting FUZE crashs, in undocked state at >500")
   count += 1
   update()
repeat

// Add element to the end of the array
function push(a, element)
   a[len(a)] = element
return a

Thanks @spikey I will take a look. I can also try it on the new patch
