Here's a list of LLVM bugs found using Csmith: http://embed.cs.utah.edu/csmith/llvm-bugs.html http://embed.cs.utah.edu/csmith/llvm-bugs.html . Plenty of these are wrong code bugs. Security-related compiler bugs very rare, but they do exist, at least in graphics shader compilers: http://www.doc.ic.ac.uk/~afd/homepages/papers/pdfs/2017/OOPSLA.pdf http://www.doc.ic.ac.uk/~afd/homepages/papers/pdfs/2017/OOPS... . My impression is that many of these shader compilers are based on LLVM, but this is mostly conjecture. (I do recall a video game crashing on me with internal LLVM errors from the graphics driver.)
