List literal with many items leads to "Maximum call stack size exceeded"

[witoldsz]

I just discovered that list literals with many items produce a code which crashes at run-time.
Look at this example: https://runelm.io/c/yca
It defines a list with 1000 items and the program will crash before it executes. Sometimes 400 items will be enough to crash the browser, sometimes 600 won't crash.

I have found this when I was trying to work with elm-community/elm-time library. The bug was filled:
elm-community/elm-time#13
Example: https://ellie-app.com/qwD8mkg9TTa1/1

Later, I have found another, unrelated issue with that lib:
elm-community/elm-time#21
and when I was trying to fix that, I have discovered I cannot even build that project, because it was crashing with Maximum call stack size exceeded during elm-test.

There is no hard limit: that very lib defines dict with all possible time zones which is c.a. 600 elements. It sometimes crashes, sometimes it does not, depends on browser and number of opened tabs.

Thanks for the issue! Make sure it satisfies this checklist. My human colleagues will appreciate it!

Here is what to expect next, and if anyone wants to comment, keep these things in mind.

Workaround: split your big list and use List.concat, example:

before =
    [1,2,3, …, n]

after =
    List.concat [ [1,2,3, …], [ 31, 32, 33, …], …] ]

That's strange, I was looking for an open issue with "maximum" and did not find it.

You are right! I was looking in elm-core.
