Subject: "make check" fails in a clang sanitizer build on "nbd-qemu-allocation" iotest
Date: Mon, 15 Nov 2021 17:11:54 +0000 [thread overview]
Message-ID: <CAFEAcA-8jo5SmV41CP6aquyWWvrQQo5OoXbac=knD4z6A3fHxw@mail.gmail.com> (raw)
Hi; running a 'make check' on a clang sanitizer build one of
the iotests falls over due to a NULL pointer being passed to
memset():
