@nez...

(Just seen Corona688 post.)

The code was written for a real stock A1200 with HDD, Motorola 68020 32 bit, no FPU nor MMU.
This is a screenshot of the FS-UAE AMIGA emulator for THIS 64 bit MBP, OSX 10.14.1, using 68040 with FPU and MMU, and much more than the stock 2MB RAM, compiling the 'error.c' code that is in the OP using the AMIGA's gcc 2.95.3.

As you can see it IS working!

EDIT:
@C688...

That makes sense but I didn't see it. However the OP's first code block will not compile in gcc 2.95.3 as it crashes out so I am stuck with an 'illegal' operation for my fav' OS.

LEARN ABOUT DEBIAN

hardened-cc

HARDENED-CC(1)							 Debian GNU/Linux						    HARDENED-CC(1)

NAME

       hardened-cc - gcc wrapper to enforce hardening toolchain improvements

SYNOPSIS

       export DEB_BUILD_HARDENING=1

       gcc ...

DESCRIPTION

       The  hardened-cc  wrapper  is  normally	used by calling gcc as usual when DEB_BUILD_HARDENING is set to 1. It will configure the necessary
       toolchain hardening features. By default, all features are enabled. If a given feature does not work correctly and needs  to  be  disabled,
       the corresponding environment variables mentioned below can be set to 0.

ENVIRONMENT

       DEB_BUILD_HARDENING=1
	      Enable hardening features.

       DEB_BUILD_HARDENING_DEBUG=1
	      Print the full resulting gcc command line to STDERR before calling gcc.

       DEB_BUILD_HARDENING_STACKPROTECTOR=0
	      Disable stack overflow protection. See README.Debian for details.

       DEB_BUILD_HARDENING_RELRO=0
	      Disable read-only linker sections. See README.Debian for details.

       DEB_BUILD_HARDENING_FORTIFY=0
	      Don't fortify several standard functions. See README.Debian for details.

       DEB_BUILD_HARDENING_PIE=0
	      Don't build position independent executables. See README.Debian for details.

       DEB_BUILD_HARDENING_FORMAT=0
	      Disable unsafe format string usage errors. See README.Debian for details.

NOTES

       System-wide settings can be added to /etc/hardening-wrapper.conf, one per line.

       The  real gcc symlinks are renamed gcc.real, and a diversion is registered with dpkg-divert(1).	Thus hardened-cc's idea of the default gcc
       is dictated by whatever package installed /usr/bin/gcc.
