Well its not possible for the assembly unwinder to do the correct thing in this
situation , as the function is entered through a stub function (which has push
instruction) and then a jump. The point of this patch is to catch when to use
the CFI or the assembly unwinde

@labath, Well the other tests in TestMultithreaded.py are not flaky and I see
the only difference as an extra push operation, so I thought the push operation
could be potential bottleneck.

Hello @ldrumm,
I did investigate the issue and my finding is that incorrect values are being
passed to the SetDataWithReadMemoryFallback function. Now I suspect the
ElfSectionHeader is wrongly parsed in your case and the size and offsets
obtained are wrong. To talk

Hi Oleyksiy, actually the problem is not with the Elf Format but its a problem
with the ObjectFileElf itself which cannot handle reading from arbitrary

The reason assembly unwind did not work is because if the ebp register is set
to 0 at that time, so the CFA is not available. In the case of clang the frame
pointer is not set by any function, which is why the formula does not work.
