--- Comment #7 from Bruno Haible <bruno at clisp dot org> --- (In reply to Richard Biener from comment #6) > For portability you likely want to convert the function pointer to uintptr_t > and only that to char */long *. That might also avoid GCCs diagnostic. Thanks for the attempted advice. But, no, converting a pointer to uintptr_t and later back to a pointer is bad for portability: It does not work on the CHERI architecture and its implementation on the ARM Morello chip https://developer.arm.com/Architectures/Morello, because it loses the tag bits that are essential for accessing the pointer. See https://www.gnu.org/software/gnulib/manual/html_node/C99-features-avoided.html and https://lists.gnu.org/archive/html/bug-gnulib/2023-12/msg00021.html .
