* bpo-40791: Make compare_digest more constant-time. The existing volatile `left`/`right` pointers guarantee that the reads will all occur, but does not guarantee that they will be _used_. So a compiler can still short-circuit the loop, saving e.g. the overhead of doing the xors and especially the overhead of the data dependency between `result` and the reads. That would change performance depending on where the first unequal byte occurs. This change removes that optimization. (This is change #1 from https://bugs.python.org/issue40791 .)

) Fix test_gdb.test_pycfunction() for Python built with clang -Og. Tolerate inlined functions in the gdb traceback. When _testcapimodule.c is built by clang -Og, _null_to_none() is inlined in meth_varargs() and so gdb returns _null_to_none() as the frame #1. If it's not inlined, meth_varargs() is the frame #1.

…python#91466) Fix an uninitialized bool in exception print context. `struct exception_print_context.need_close` was uninitialized.
