SQLite.swift Crash when accessing in multi-threaded environment

Build Information

Application is written in Swift 4 Using SQLite.swift 0.11.4 via CocoaPods Xcode 9.3.1

Crash Information

I'm experiencing a crash in sqlite3_prepare_v2 which gets called from Connection.prepare or Connection.pluck on devices running iOS 9 & iOS 10. The connections are accessed in a multi-threaded environment and works fine on iOS 11 and above.

Below is a screenshot of the exact place where the crash happens:

What might be the possible reason for this. TIA

try! connection.run("CREATE TABLE Records (id INTEGER, name TEXT NOT NULL)")

for _ in 0 ..< 100 {
    DispatchQueue.global().async {
        _ = try? connection.scalar("SELECT COUNT(*) FROM Records")
    }
}
DispatchQueue.global().async {
    try! connection.transaction(.exclusive) {
        try connection.run(Table("Records").drop(ifExists: true))
    }
