a little clarification on my debug points:
breakpoint 1 : perf_reader.cc:1325 SeekSet(section_iter->offset);>
breakpoint 2 : buffer_reader.cc:12 <if (offset_ + size > size_)>
breakpoint 1
section_iter->offset == 0x50000100000001
section_iter->size == 0xffffffff
breakpoint 2:
size_ == 0x15d7e030
size == 8
offset_ == 0x50000100000001
backtrace at breakpoint 2:
