rats_tls_init()@L149: detect memory leak in host mode

[Ben-cpy]

Steps to reproduce ( in Alibaba Cloud Linux 3 with openssl 1.1.1 and clang 15.0.7)

# 1.install clang
yum install -y clang

# 2.build in the host mode
cmake -DRATS_TLS_BUILD_MODE="host" -DBUILD_SAMPLES=on -DBUILD_FUZZ=on -H. -Bbuild
make -C build install

# 3. generate random corpus
cd /usr/share/rats-tls/fuzz
mkdir corpus && cd corpus
base64 /dev/urandom | head -c 1500000 > random.txt
cd ..

# 4. run fuzz program
./fuzz_init -max_len=1500000 -len_control=0  corpus

you can use nullattester,nullverifier,nulltls , nullcrypto to replace the randon instance selection in fuzz_init.cc to make memory leak more easily to trigger. forfuzz_init.txt you should change its suffix into fuzz_init.cpp and change the correponding Cmake file name too error.log is the output of libfuzzer output

The error is
