Unable to generate constants introduced in error handling

[CryingN]

Describe the bug

In the newer versions, when constants are introduced using import and if they are only imported for error handling, the variables will not be defined after compilation to C.

Reproduction Steps

there is a simple example. When using the following code, it fails to compile properly:

import db.sqlite
import math

@[table: 'personal']
pub struct Personal {
        pid             int                 @[primary; sql:serial]
}


pub fn connect_db() sqlite.DB {
    mut db := sqlite.connect('./data.db')  or {
        println('Error: sqlite调用错误')
        panic(err)
    }
    return db
}


pub fn create_db(db sqlite.DB) {
    sql db {
        create table Personal
    } or {
        println(math.pi)
    }
}

fn main() {
    mut db := connect_db()
    create_db(db)
}

Expected Behavior

Under normal circumstances, it should compile successfully.

Current Behavior

return:

================== C compilation error (from tcc): ==============
cc: /tmp/v_1000/sql_db.01JQ667HSZ6YXR64C12Q540344.tmp.c:10105: error: '_const_math__pi' undeclared
=================================================================
(You can pass `-cg`, or `-show-c-output` as well, to print all the C error messages).
builder error:
==================
C error found. It should never happen, when compiling pure V code.
This is a V compiler bug, please report it using `v bug file.v`,
or goto https://github.com/vlang/v/issues/new/choose .

when test.v to test.c, I can't find define _const_math__pi, but in line: 10105, there is:

[root_cn@archlinux sql_db]$ cat test.c | head -n 10107 | tail -n +10103
        if (_t2.is_error) {
                IError err = _t2.err;
                println(float_literal_str(_const_math__pi));
        ;
        }
