Version Information

  • vyper Version (output of vyper --version): v0.3.3

What's your issue about?

the following code would generate impractically large bytecode. the compiler hangs instead of raising an error.

struct StructNull:
  val: uint256

struct StructOne:
  structs: StructNull[MAX_UINT256]

map:public(HashMap[uint256,StructOne])

How can it be fixed?
