Compilation Error When Building Exiv2 with afl-clang-fast/afl-clang-fast++

When I am trying to fuzz `exiv2` with AFL：
```
git clone https://github.com/Exiv2/exiv2.git

cd exiv2
cmake -S . -B build2 \
-DCMAKE_C_COMPILER="/home/AFLplusplus/afl-clang-fast" \
-DCMAKE_CXX_COMPILER="/home/AFLplusplus/afl-clang-fast++" \
-DCMAKE_BUILD_TYPE=Debug \
-DEXIV2_TEAM_USE_SANITIZERS=ON \
-DBUILD_SHARED_LIBS=ON \
-DCMAKE_CXX_STANDARD=20 \
-DEXIV2_ENABLE_CURL=ON \
-DCMAKE_IGNORE_PATH="/root/miniconda3/lib"Duplicate of
cmake --build build2 2>&1 > compile-log
```
Then, crash happened. Since the project instructions mention submitting issues here, I create this issue accordingly, hoping it will help with improvement!
```
clang++: /usr/lib/llvm-14/include/llvm/Support/Casting.h:269: typename cast_retty::ret_type llvm::cast(Y *) [X = llvm::Instruction, Y = llvm::Value]: Assertion `isa(Val) && "cast() argument of incompatible type!"' failed.
PLEASE submit a bug report to https://github.com/llvm/llvm-project/issues/ and include the crash backtrace, preprocessed source, and associated run script.
