>Description:
hexcalc gets wrong result for some functions (like 2+5)

This is due to gcc optimizer handing of questionable code in the program.
(works fine compiled without optimization)

See http://bugs.gentoo.org/show_bug.cgi?id=140987 for details.
>How-To-Repeat:
install hexcalc from ports. add 2+5= (get wrong result '4')
>Fix:
apply patch from http://bugs.gentoo.org/show_bug.cgi?id=140987
