GCC C++ Compilation Error After macOS Sequoia 15.4 Update

After updating to macOS Sequoia 15.4, I'm encountering errors when compiling C++ code using GCC. This issue did not occur in the previous version of macOS. I haven't made any changes to my development environment apart from the system update. Has anyone else experienced this, or is there an official workaround or fix? I researched a bit about this error and got to know about issue with apple headers in the new update. Link

I have also attached a screenshot of my error here.

Well, this may be no further help, but I was running into the same issue and

> brew reinstall gcc

fixed the issue. This is on Sequoia 15.4.1.

After updating to macOS 15.4 today, I encountered the same issue. However, reinstalling GCC via Homebrew resolved the problem.

Based on https://gcc.gnu.org/bugzilla/show_bug.cgi?id=119590 and a few other reports, this looks to be an Apple bug (FB17100494).

Kind of amusing that by default, homebrew used Apple's command line tools for Xcode (clang/clang++) to compile GCC… into Mac architecture native build.

Can you please delineate the steps you took? I tried reinstalling GCC, but it didn't work for me.
