Re: [Simulavr-devel] [bug #47017] regression of Bug 34793

[Michael Hennebry]

If the problem is gcc-specific, the following might be an appropriate 
workaround:
#ifdef __GNUC__
default: __builtin_unreachable();

#endif

    _______________________________________________________

Details:

Presumably due to optimization improvements on newer gcc

gcc version 5.3.1 20151207 (Red Hat 5.3.1-2) (GCC)

disp.c:246:34: error: variable ‘areg’ set but not used
[-Werror=unused-but-set-variable]

The attempted fix in the code is:
                    areg = 42;          /*
http://gcc.gnu.org/bugzilla/show_bug.cgi?id=34793 */
