UIWebView WebCore TimerBase仅在11.3（15E216）上崩溃：SIGTRAP WebCore _ZN7WebCore9TimerBaseD2Ev
我最近收到了Crash Report Tools的崩溃报告。 这个崩溃是指UIWebView WebCore崩溃，我的应用程序只使用UIWebView，而我最近无法切换到WKWebview。 下面是崩溃报告，我无法重现它。 它发生在iPhone 6,7,8，X设备上，但只使用iOS 11.3版本（15E216）。
这次崩溃有3个不同的崩溃堆栈。 任何意见将是有益的。

有谁能够帮助我 ？ 🙂
由于JavaScriptCore我遇到了同样类型的问题。 浪费了3-4天的时间，最后得到了解决方案。
对于iOS 11.0，只需将
JSC_useJIT环境禁用为false即可。 这对我有用。
我将此代码放在AppDelegate文件中的didFinishLaunchingWithOptions方法中：
setenv("JSC_useJIT", "false", 0);
我希望这将有所帮助。
从这里找到参考
您似乎已在WebKit中暴露了TimerBase的错误，如下所示： https ：//bugs.webkit.org/show_bug.cgi？id = 182931
他们提到了一个修复，可能已经在最近发布的11.3.1中找到了。
如果你很好奇，你可以在这里看到修复 。
