Subject: range-set: Add test coverage for range_set_destroy(NULL).
X-Git-Tag: v0.7.3~101
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?p=pspp-builds.git;a=commitdiff_plain;h=a091aa55567a4f2a9ecc08f126a959497be43f22

range-set: Add test coverage for range_set_destroy(NULL).

"gcov -b" showed that range_set_destroy() was never called with a NULL
argument.  There's no reason not to test that too (although of course it
is unlikely to be broken).
