My two cents:

In the early version of CentOS 10 stream, with gcc-14.1.1-5.el10.x86_64, there is no compile error for cve-2015-3290.c

But when I update gcc to gcc-14.2.1-6.el10.x86_64, I hit the same issue as Ma.

Seam like commit cbfad3ba CFLAG -fomit-frame-pointer does not works at all.

I see some articles describe about frame pointers[1], -fomit-frame-pointer should work...

Does this issue a GCC bug or a new feature which deprecated something?
