It looks like you failed 1 out of 7 tests.

The expected result is to find a non-existent path, but the test case reports an error Failed. Does this test case need optimization?

Probably a duplicate of #23277.

Probably a duplicate of #23277.

ok Thanks

[lillianokok]

Probably a duplicate of #23277.

But I fixed it according to the method of #23339, and the problem still exists. What should I do?

@lillianokok, can you please supply the output of perl -V for the perl build in which you are observing this problem?

(Without that it is difficult for someone to try to reproduce your problem.) Thanks.
