I am trying to build jdk18u on RHEL9 using GCC 11.3.1.
I am able to build it with no problems on RHEL8 using GCC 8.3.1.
I am able to build it with no problems on Fedora 29 using GCC 8.3.1.
But on RHEL9/Fedora 34/Fedora 36 using GCC 11.3.1/12.1.1 (the default for these distros) I get the following error:
```

Has anyone tried compiling this on RHEL9 or Fedora >= 34 / GCC >= 11.3.1?
Does anyone know of a workaround to get this to compile on these platforms/with these compilers?
