Minified sample

Same here. I don't think it is just a memory hog; compiler probably enters some
kind of infinite loop.
Tested on 4.9.2, 4.9.3 and 5.2.0. Command line to reproduce is
"x86_64-pc-linux-gnu-gcc -m32 -O2 -floop-interchange -c fram_gen.c". It only
happens when using this specific combination of flags (32-bit mode, O2 and loop
interchange enabled).
