Emacs crashes on startup if it's compiled with the current mainline on x86-linux.
The crash happens becase one file seems to be miscompiled: src/alloc.c
compiling just that one file with -O1 -fno-tree-loop-optimize and everything
else with -O2 results in a working emacs. If src/alloc.c is compiled with -O1
and all the other object files are kept the same, the resulting emacs crashes on
startup.
