recursive struct causes execution error.
Version: v0.3.3: Atlantis Description: s2 is a recursive struct, and inner.recursive[0].z = inner.recursive[1].z + 1; causes the program to throw an error. However, solc+EVM can execute it successfully.
contract test {
struct s2 {
uint32 z;
mapping(uint8 => s2) recursive;
}
s2 data;
function set() public {
data.z = 2;
mapping(uint8 => s2) storage map = data.recursive;
s2 storage inner = map[0];
inner.z = 3;
inner.recursive[0].z = inner.recursive[1].z + 1;
}
}
Reproduction: I set up a Solang compilation and execution environment to test the program.
solang/target/debug/vmRunNoPara test.sol test set
The execution error is as follows:
