Sorry, I don't understand: what does it mean "terminal with gcc X.= Y.Z
loaded"? how is GCC "loaded" in those cases?

Sorry, I used the wrong term.. meant to say shell inst= ead of terminal. At work, we have a "module" system that allows l= oading different versions of various applications on the fly. So if I have = 2 terminals open, I can have different versions of gcc in them.
T= here's a default gcc version that's older (9.1.0) and then the gcc = version I use to build emacs which is slightly newer (9.3.0).

That's not a requirement.=C2=A0 What _is_ a requirement is that when yo= u
upgrade your GCC installation, you need to restart Emacs, if the
running Emacs session was built with native compilation, so that Emacs
starts using the version of GCC that you have installed for future
compilations.=C2=A0 But the *.eln files that were built by libgccjit of one=
version should be fully usable after you upgrade to another version.

I did do a complete restart of emacs/emacscli= ent. I ensured using ps that no emacsclient sessions were running in the ba= ckground.

If I have gcc 9.1.0 paths (PATH, LD_LIBR= ARY_PATH, etc.) loaded in the shell, I see this issue.
But once I= switch to gcc 9.3.0 paths, the issue is fixed.

That error doesn't come from Emacs, it comes from the GCC compilation driver.=C2=A0 We just report it, as it was reported to us.

OK.=C2=A0
