[PATCH v2 1/9] test-tool test-hash: fix a memory leak

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Fix a memory leak in "test-tool test-hash" which has been there since
b57cbbf8a86 (test-sha1: test hashing large buffer, 2006-06-24), as a
result we can mark more tests as passing with SANITIZE=leak using
"TEST_PASSES_SANITIZE_LEAK=true".
