[PATCH v3 3/6] tr2: stop leaking "thread_name" memory

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

 



Fix a memory leak introduced in ee4512ed481 (trace2: create new
combined trace facility, 2019-02-22), we were doing a free() of other
memory allocated in tr2tls_create_self(), but not the "thread_name"
"struct strbuf".
