--- Comment #4 from Ev Drikos <drikosev at gmail dot com> --- Created attachment 45574 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=45574&action=edit program output & gcc configuration in Sierra Hello, Having run this small test in older systems also, Yosemite (10.11) and sierra (10.12), I see that the results vary. I can reproduce the problem in Yosemite, not in Sierra. IMHO opinion, this issue depends either on GNU GCC configuration or to some patch I've applied in the meantime. My guess is that the reason is likely the configuration. Ev. Drikos
