Thanks, this seems like trying to access a fence which already was released,
but i can't pinpoint the faulting line in the code both for
amdgpu_sync_get_fence and for amdgpu_sync_resv, I am using addr2line for this
but the offset into the function shown in the backtrace doesn't make sense.
Maybe because our builds differ, can you try it and see if you get the exact
offending lines in both functions ?
