Law <law at redhat dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |law at redhat dot com --- Comment #18 from Jeffrey A. Law <law at redhat dot com> --- I've been able to reproduce this under arm-qemu. Start by bootstrapping and installing gcc-4.9.4. Then use that gcc-4.9.4 to build gcc-5.3.0 and you'll get the comparison failure. Based on various comments I strongly suspect this is a bug in gcc-4.9.4.
