[Christian Heimes]

Christian Heimes <lists at cheimes.de> added the comment:

I'm using an ASAN UBSAN build of Python:

$ make clean
$ ./configure --with-address-sanitizer --with-undefined-behavior-sanitizer
$ cat > asan-suppression.txt << EOF
# Python/initconfig.c
leak:_PyWideStringList_Copy
EOF
$ LSAN_OPTIONS="suppressions=asan-suppression.txt,print_suppressions=0"  make
$ LSAN_OPTIONS="suppressions=asan-suppression.txt,print_suppressions=0" ./python -m test test_eof
