这问题复现大约又得等一周了,还木有解决,关于SIGBUS我找到了下面的解释,分享一下:
Invalid address alignment
The program has attempted to read or write data that does not fit the CPU's memory-alignment rules.
Non-existent physical address
This is equivalent to a segmentation fault, but for a physical address rather than a virtual address.
Object-specific hardware error
This is far less common, but it is present in Linux and Solaris, when virtual memory pages have disappeared
