I think this memory leak is actually required in this case. SAL_NO_ACQUIRE
means that the ref count of the internal pipe object is not incremented and
therefore during the destruction of the osl::Pipe we are now deleting the
same internal object twice.

I think this can be seen in
https://ci.libreoffice.org/job/lo_ubsan/611/consoleFull and IMHO the
easiest fix might be to just annotate that test for coverity. Maybe someone
has a better idea.
