2016-12-11 Thread Santiago Vila
Greetings. Could anybody tell me is this optimization bug on ARM was finally fixed... * in gcc-4.9 as released with jessie? * in gcc-6 as the default compiler in stretch? I ask because I added this workaround to unzip's debian/rules: ifeq ($(DEB_HOST_ARCH),armhf) CFLAGS := DEB_CFLAGS_STRIP=-O
