That was, for the most part, just a problem with LLVM governance and development priorities. When the bugs were found in LLVM, GCC was examined and found to have a few similar bugs. GCC fixed these issues relatively quickly, but LLVM sat on them for years. Normal C/C++ developers doing normal C/C++ development in GCC probably never saw any of those bugs.
