Created attachment 36177

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).

Fixed in trunk gcc with a recent ISL-0.15 that has compute out functions.
$ time gcc -m32 -O2 -floop-interchange minified.i -S
real 0m0.129s
$ time gcc -m32 -O2 -floop-interchange preprocessed.i -S
real 0m1.678s
