Android 致命信号 7 (SIGBUS)
我遇到了一些难以追踪的 SIGBUS (7) 和 SIGSEGV (11) 崩溃问题.
I'm getting a few SIGBUS (7) and SIGSEGV (11) crashes that I am having difficult tracking down.
似乎导致崩溃的线程主要用于加载要显示的图像，这是有道理的，因为日志表明 SkJPEGImageDecoder 出现故障.
The thread that appears to be causing the crash is primarily used for loading images to be displayed which makes sense since the logs indicate something failing with the SkJPEGImageDecoder.
我根据此 Bitmaps 重新使用内存"noreferrer">指南
I re-use memory for Bitmaps in accordance with this guide
会不会跟这个有关?

根据这个 document，看来 SIGBUS 7 是数据错位问题，而 SIGSEGV 11 是写入无法访问的内存.
As per this document, it appears that SIGBUS 7 is a data misalignment issue, and SIGSEGV 11 is a write to inaccessible memory.
推荐答案
您的错位在地址 0x0000001e.这是一个非常奇特的地址——几乎可以肯定它是错误的.很可能您在某处传递了一个空指针，而 C 库试图在 30 个字节处对其进行数组访问，或者它认为它是一个类并试图访问某个 30 个字节处的成员变量.无论哪种方式我会对甚至可以远程调用图像库的任何内容进行空检查，并对任何位图对象进行 isRecycled 检查，以查找您传递错误值的位置.
Your misalignment is at address 0x0000001e. That's a very peculiar address- it's almost certain to be wrong. Most likely you're passing in a null pointer somewhere and the C library is trying to either do an array access into it at 30 bytes in, or it thinks its a class and is trying to access some member variable 30 bytes in. Either way I'd put null checks around anything that could even remotely call into the image libraries, and put isRecycled checks around any bitmap objects to find where you're passing in bad values.
