The Free Pascal Compiler (FPC) is a compiler that translates Pascal source code into executable programs. Developers use it to build applications, often alongside the Lazarus integrated development environment. A compiler is part of the software supply chain: it turns human-written code and its dependencies into binaries that can run on a system.
In cybersecurity, toolchain integrity matters because compromised or untrusted build inputs can affect the resulting software. When workflows use packages that are loaded or linked dynamically, teams should verify package origin, integrity, and version, and review changes to how components are selected. Dynamic package support alone does not indicate a vulnerability; it makes clear trust and review practices important.
