From: Ed Bartosh <eduard.bartosh at intel.com>
First parameter of traceback.format_exc APIs is a 'limit' - a
number of stracktraces to print.
Passing exception object to print_exc or format_exc is incorrect,
but it works in Python 2 and causes printing only one line of traceback
as exception object is compared with the integer counter in the
traceback module code.
In Python 3 comparison of integer and exception object throws
an exception:
TypeError: unorderable types: int() < <Exception type>()
As format_exc is used in except block of handling another
exception this can cause hard to find and debug bugs.
