Use-of-uninitialized-value waring with MSAN in AudioFile

[Yhcrown]

Hi, Adam: When I use msan to run AudioFile's exmaple program, it outputs the following error message:

Uninitialized bytes in MemcmpInterceptorCommon at offset 48 inside [0x7fffcb727450, 256)

Although this does not necessarily bring any high-risk effects, I still think it is an abnormal result, and hope to get your attention

Verification steps：

git clone https://github.com/adamstark/AudioFile.git
cd AudioFile/
git checkout develop
mkdir check_build && cd check_build
cmake ../ -DCMAKE_C_COMPILER=clang  -DCMAKE_CXX_COMPILER=clang++ -DCMAKE_C_FLAGS="-fsanitize=memory" -DCMAKE_CXX_FLAGS="-fsanitize=memory" 
make -j 
cd examples
