[New-bugs-announce] [issue36155] ./python -m test -m test_gc fails

[Karthikeyan Singaravelan]

New submission from Karthikeyan Singaravelan <tir.karthi at gmail.com>:

I am not sure of the exact cause about this failure but `./python.exe -m test -m test_gc` fails though `./python.exe -m test -v test_gc` passes. This test was recently added with 175421b58cc97a2555e474f479f30a6c5d2250b0 and issue36016.
