Description
while works fine when it iterates a couple of times but at some number of iterations it fails. In the example below the number of iterations were between 64 and 65 000 times:
🦄 .editor
// Entering editor mode (^D to finish, ^C to cancel)
let a = 1
while(a>0) {
if ((a/1000):equals(floor(a/1000))) {
log(a)
}
a=a+1
}
1000
2000
3000
4000
5000
6000
7000
8000
9000
10000
11000
...
62000
63000

Research direction
Reproduce the loop from the issue at commit f527c5c, then inspect dist/utils/index.js and askvm/resources/core/call.js alongside the reported Node async_hooks stack. Trace what changes after many iterations and verify that the while loop can continue past the failure range without the reported RangeError.
