Functions which are free'd are not immediately removed from the binary as this would cause a shifting of function indexes. Instead, they hang around until they can be overwritten by a new function. This means that the types associated with these dead functions must also remain until the function is overwritten to avoid a type mismatch.

Building from Source
Note that you can download a binary of master branch.
Stage 1: Build Zig from C++ Source Code
Dependencies
POSIX
- cmake >= 2.8.5
- gcc >= 5.0.0 or clang >= 3.6.0
- LLVM, Clang, LLD development libraries == 10.x, compiled with the same gcc or clang version above
- Use the system package manager, or build from source.
Windows
- cmake >= 3.15.3
- Microsoft Visual Studio. Supported versions:
- 2015 (version 14)
- 2017 (version 15.8)
- 2019 (version 16)
- LLVM, Clang, LLD development libraries == 10.x
- Use the pre-built binaries or build from source.
Instructions
POSIX
mkdir build
cd build
cmake ..
make install

MacOS
brew install cmake llvm
brew outdated llvm || brew upgrade llvm
mkdir build
cd build
cmake .. -DCMAKE_PREFIX_PATH=$(brew --prefix llvm)
make install
You will now run into this issue:
homebrew and llvm 10 packages in apt.llvm.org are broken with undefined reference to getPollyPluginInfo
or
error: unable to create target: 'Unable to find target for this triple (no targets are registered)',
in which case try -DZIG_WORKAROUND_4799=ON
Hopefully this will be fixed upstream with LLVM 10.0.1.
Windows
