Subject: [Bug target/45063] [4.6 Regression] ICE: Segmentation fault (cc1) compiling matmul_i1.c

It sounds like the compiler is being miscompiled? If so, it's probably not
helpful trying to debug the miscompiled compiler binary. The best way to debug
this would be to produce one working build and one failing build of the
compiler, then narrow down which file is being miscompiled by copying over
object files from one directory to another. You may have a candidate already
in the code you're looking at.
Once that's identified, please attach a .i of the file that's being
miscompiled, and the exact command line options to give cc1 to reproduce the
miscompilation. A set of good/bad .s files might also help.
