In 'poll_partial_rec_async' a uninitialized char variable 'token' with *garbage* value is used for write/read instruction to synchronize between threads via a pipe. tls.c:2833:26: warning: variable 'token' is uninitialized when passed as a const pointer argument here [-Wuninitialized-const-pointer] 2833 | EXPECT_EQ(write(p[1], &token, 1), 1); /* Barrier #1 */ Initialize 'token' to '\0' to prevent write/read of garbage value.
