The error handling component cannot output all compile-time errors.

[haoyang9804]

Description

The following test program includes two compile-time errors: 1) struct_instance9, of storage pointer type, is accessed without prior assignment; and 2) Type uint256 is not implicitly convertible to expected type uint64 at line uint64 a = 11 << b;.
However, the second error seems to suppress the throw-out of the first error message. The compiler only reports the second error. If I comment out the whole contract C, the first error will be reported.

contract contract0 {
  struct struct1 {
    bool b;
  }

  function func5() public returns (uint256 var7) {
    struct1 storage struct_instance9;
    return struct_instance9.b ? 1 : 0;
  }
}

contract C {
  function f() external returns (uint64 b) {
    uint64 a = 11 << b;
  }
}

Environment

• Compiler version:0.8.28-develop
