A testcase for the fix should be added to the glibc testsuite (this
applies to any bug fix that can reasonably be covered in the testsuite and
isn't fixing an existing test failure). (It's probably a good idea to add
a test for wprintf as well to verify that wprintf continues to behave as
expected, if this isn't already covered by existing wprintf tests.)
