描述：debug 'phxbinlogsvr_phxrpc'时候，attach上去后，每次在调用phxbinlog::EventIndex::OpenDB时候，leveldb::DB::Open返回的status.ok 失败，请问是我调试手段有问题还是哪方面没有理解正确？期望，给予提示！！ 10x 0x00007ffff6efec25 <+37>: mov %eax,%esi 11x 0x00007ffff6efec27 <+39>: movslq %edi,%rdx 12x 0x00007ffff6efec2a <+42>: movslq %esi,%rsi 13x 0x00007ffff6efec2d <+45>: movslq %ecx,%rdi 14x 0x00007ffff6efec30 <+48>: mov $0xea,%eax 15x 0x00007ffff6efec35 <+53>: syscall 16tqq> 0x00007ffff6efec37 <+55>: cmp $0xfffffffffffff000,%rax 17x 0x00007ffff6efec3d <+61>: ja 0x7ffff6efec5d <__GI_raise+93> 18x 0x00007ffff6efec3f <+63>: repz retq 19x 0x00007ffff6efec41 <+65>: nopl 0x0(%rax) 20x 0x00007ffff6efec48 <+72>: test %ecx,%ecx 21x 0x00007ffff6efec4a <+74>: jg 0x7ffff6efec27 <__GI_raise+39> 22x 0x00007ffff6efec4c <+76>: mov %ecx,%eax ** Dump of assembler code for function __GI_raise: (7ffff6efec00 - 7ffff6efec6d) **
