With "-fno-tree-pre" we still die in global.c, only somewhere else this time: 
 
#0  xmalloc_failed (size=4072) at xmalloc.c:118 
#1  0x00000000007c7777 in xmalloc (size=Variable "size" is not available.) at 
xmalloc.c:145 
#2  0x0000002a956d8ff7 in _obstack_newchunk () from /lib64/tls/libc.so.6 
#3  0x0000000000505ea6 in bitmap_elt_insert_after (head=0x7fbfffe230, 
elt=0x1b7ade30) at bitmap.c:110 
#4  0x0000000000506f2b in bitmap_and_compl (dst=0x7fbfffe230, a=Variable "a" 
is not available.) at bitmap.c:661 
#5  0x0000000000507017 in bitmap_ior_and_compl (dst=0x4803960, a=0x4803900,

#6  0x000000000076628d in make_accurate_live_analysis () at global.c:2307 
#7  0x00000000007663ed in global_alloc (file=0x0) at global.c:347 
#8  0x0000000000713123 in rest_of_compilation () at passes.c:529 
 
Not really surprising, given this: 
(gdb) p max_regno 
$6 = 65597
