Re: Bug#764732: gcc-4.9: broken -O2 optimizations on armhf

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

the escalation is wrong. there exist several workarounds for it (lowering the optimization, using gcc-4.8, ...). I asked the ARM porters to address this properly (Hector on IRC agreed to forward this), however I don't see any progress here. Now CCing debian-arm explicitly. On 12/23/2014 11:48 AM,
