error when convert perf record data to profile

[michaelrun]

Hi, experts
I built autofdo relevant binaries from source code 'master', and after I collected some perf.data, I use create_gcov to do the conversion, but it always reports error like below:

[ERROR:/home/guoqing/autofdo/autofdo/third_party/perf_data_converter/src/quipper/perf_reader.cc:191] Illegal perf_file_section.offset 15762598695796815 in perf data input of size 3334833272
[ERROR:/home/guoqing/autofdo/autofdo/third_party/perf_data_converter/src/quipper/perf_reader.cc:1228] Error reading metadata entry info.
[ERROR:/home/guoqing/autofdo/autofdo/profile_creator.cc:182] Error reading profile.

it seems perf_file_section.offset is always 15762598695796815 , no matter the size of perf file. Do you have any idea why this happens, and how to fix/workaround?

Could you share an example perf.data? Or the perf command you used to collect one?
