The bug tracker at https://gcc.gnu.org/bugzilla has lots of issues that were present in GCC 11.2.0 and either fixed in later releases or not fixed yet. Why are you using 11.2.0 and not 11.5.0? There are lots of bugs in 11.2.0 that were fixed in later releases from the gcc-11 branch. In addition to the bugs in bugzilla, all support for C++20 and later standards is unstable in GCC 11. I'm sure there are other unstable APIs. You're asking us to prepare a large list of all known issues in GCC 11, which is not something anybody is going to do for you, because it's a lot of work.
