[UE 5.4][Android] Assertion failed: FPlatformTLS::IsValidTlsSlot(ThisTlsSlot)

目前在引擎5.4版本，安卓develop版本，部分安卓机型出现的概率比较大，研究了下源码，感觉是pthread_key_create已经创建失败了，引擎本身使用了很多TThreadSingleton，加上我们接入的SDK也用了pthread_key，因此耗尽了，想问下有什么处理方式么？

Hi,

我们没有在Android平台遇到过，但是在window遇到过，针对windows我们做了一些限制，具体改动CL#27827939，我估计需要针对android平台做类似的改动。

4

感谢答复，我们观察到，之前CL#34031139 引擎已经做了一些针对tls的优化，但是后续又回滚了，是什么原因呢？看着改动的细节跟我们遇到的问题比较相符。

Hi，

我看了一下历史纪录，没有提示回滚的原因，我正在问开发的同事，如果后续有结果，我会再同步给你。但这个fix看起来是想修复类似的问题，这是平台不是针对android做的。

Hi，

同事反馈说 it was causing problem with static initializer / dyn tls initialization，具体情况可能记不清了，你可以合入试试，看看是否遇到什么具体问题。（可以考虑只让改动对Android平台起效）。

多谢解答 我们这边再试试看看
