[Bug]: TypeError in solc_parsing/declarations/contract.py, line 775, in _handle_comment

[duckki]

Describe the issue:

Certain comments cause the solc_parsing to crash.
It appears to happen with Solidity 0.6 and 0.5, but not with 0.7 and 0.8.

Code example to reproduce the issue:

// SPDX-License-Identifier: UNLICENSED
pragma solidity ^0.5.0;

/**
 * @dev text
 */
contract Test {
}

Version:

0.9.2

Relevant log output:
