[RingoD]

I see the console logs are odd, containing a lot of warning messages. Maybe you could check whether they are related.

In addition, you can try to use WCDB after the application:didFinishLaunchWithOptions: returned, and see if it's fixed.

If the ways above don't help, you could provide a demo project that can reproduce this crash.

[jiangpengyun]

相同问题， @RingoD 或许可以直接联系下？？
我可以提供很详细的代码细节

[jiangpengyun]

@zhuozhibin 遇到相同问题
看上去你那边现场信息丰富的多
有时间的话联系下

[RingoD]

@jiangpengyun If it's reproducible there, you can submit a demo project.

[zhuozhibin]

@jiangpengyun
我这边之前的用法是这样的：当需要用到WCDB时，就使用initWithPath获得一个WCTDatabase，用完之后就close，不同模块可能会在不同线程并发调用initWithPath或close(不知道这样使用是否有问题)，如下

module1（thread1）
func1 {
WCTDatabase *db = [[WCTDatabase alloc] initWithPath:dbPath];
...
[db close];
}

module2（thread2）
func2 {
WCTDatabase *db = [[WCTDatabase alloc] initWithPath:dbPath];
...
[db close];
}

目前改成使用一个单例模式，只init一次WCTDatabase，不同模块获取的是相同的WCTDatabase，暂时没有出现问题了（之前是10次有7，8次会崩，改了之后暂时还没出现问题）。

你这边能否提供重现demo？

抱歉没办法提供demo，我这边概率极其低，调试过程中就只出现过一次，Xcode还崩掉了。。。看到有外网版本崩溃上报，crash率千分之2左右。你方便提供一个demo出来一起研究下么？

[RingoD]

We get a project that can reproduce this crash, except the exception code is EXC_BAD_INSTRUCTION different from the OP by EXC_BAD_ACCESS.

It may or may not be a same issue. We will work on it.

[RingoD]

Here is the conclusion of this issue:

The crash reason is,

1. Config is designed as thread-safe, but there should be a bug that makes this not happen.

To solve this, there are two choices:

The simple way is to avoid this crash by NOT accessing initWithPath: or setConfig: interface concurrently. Typically, developers should init one WCTDatabase instance and reuse it.

The complete solution is to use the pre-version in pre_v1.1.0 branch. It's stable now, but there should be a lot of hard work for compatibility.

1. It's not source compatible, comparing with v1.0.x version. Developers should update there own code.
2. Cocoapods is not prepared, while Carthage and Source code compilation work well.
3. Documentation is not prepared. But if you are familiar to WCDB, it's easy for you, especially it contains test case code for each interface.
