  1. Fix GCC frame-address Regression test failure on Linux with clang 18.1.8 

    SingleSource/Regression/C/gcc-c-torture/execute/frame-address.c fails
on Linux/X86_64 with the following error:
Abort

Even though the code in frame-address.c tries to prevent tail call optimizations,
clang still elides stack frames when O3 is enabled.

This patch uses volatile function pointers to
prevent the stack frame elision in frame-address.c
