------- Additional Comments From steven at gcc dot gnu dot org 2004-12-07 09:40 ------- 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, from1=Variable "from1" is not available.) at bitmap.c:1120 #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
