Companies/tools like Coverity do source code analysis to find security/stability defects, mainly on C++ code, but these tools also are available for other languages.
IIRC, they perform checks free of charge for a number of open source projects.

Just for interest: is there a similar product available for Delphi/FPC?

Thanks,
