SEGV_ACCERR when ComputeHashCode in art

[Andrew Wiggin]

Hi, i encountered an art native crash, backtrace as below:

03-10 00:00:04.435 F/DEBUG ( 5138): #00 pc 00000000003bed48 /system/lib64/libart.so (art::mirror::String::ComputeHashCode()+84)

the corresponding source like below:

int art::ComputeUtf16Hash<unsigned short>(unsigned short const*, unsigned long) at art/runtime/utf.h:81

 (inlined by) art::mirror::String::ComputeHashCode() at art/runtime/mirror/string.cc:71

can anybody help analyse?

Thanks!
