C++ Call Stacks

terminate called after throwing an instance of 'paddle::platform::EnforceNotMet'
what():

--------------------------------------------
C++ Call Stacks (More useful to developers):
--------------------------------------------
0 std::string paddle::platform::GetTraceBackString(std::string const&, char const*, int)
1 paddle::PaddleBuf::Free()
2 paddle::PaddleTensor::~PaddleTensor()

----------------------
Error Message Summary:
----------------------
Error: An error occurred here. There is no accurate error hint for this error yet. We are continuously in the process of increasing hint for this kind of error check. It would be helpful if you could inform us of how this conversion went by opening a github issue. And we will resolve it with high priority.

[Hint: Expected length_ > 0UL, but received length_:0 <= 0UL:0.] at (/paddle/paddle/fluid/inference/api/api.cc:107)

已放弃

Start with the reported C++ stack, especially paddle::platform::GetTraceBackString, PaddleBuf::Free, PaddleTensor::~PaddleTensor, and /paddle/paddle/fluid/inference/api/api.cc:107. Reproduce the conversion that leaves length_ at 0, then determine the intended error handling and confirm the result no longer aborts.
