[New-bugs-announce] [issue43189] <test.support> decorator function run_with_locale() crashes Python interpreter

[Yang Feng]

New submission from Yang Feng <charles.fy at foxmail.com>:

We use run_with_locale() as decorator function, then we recursively call test_float__format__locale in the following example. Python interpreter crashes.
+++++++++++++++++++++++++++++++++++++++++++
from test.support import run_with_locale

@run_with_locale('LC_NUMERIC', 'en_US.UTF8')
def test_float__format__locale():
	test_float__format__locale()
test_float__format__locale()
+++++++++++++++++++++++++++++++++++++++++
