Bug ID: 64364
Summary: gcc ICE on min() on Intel Sandy Bridge CPU if compiler
built on Haswell
Product: gcc
Version: 4.9.2
Status: UNCONFIRMED
Severity: normal
Priority: P3
Component: target

failing pre-processed source
I have a freshly bootstrapped gcc 4.9.2 that I built on CentOS 5.8 on an Intel
Haswell processor (4th gen Core i5). I transferred the build over to an older
machine - same OS but running a Sandy Bridge processor (2nd gen Core i5).
Compiler crashes compiling 'min()' in limits on the SB machine, but of course
compiles fine on the Haswell one.
$ cat foo.cc
#include <limits>
$ g++ -c ~/foo.cc
