I verified that @146817 is not causing the current 32-bit breakage; I'll open a
separate PR.

Yes, I've seen similar problems with 4.4.0 and 4.5.0 on x86. Probably the
stack realignment stuff. I'd suggest opening a new PR.

This appears to still be broken in 32-bit mode.
I just built GCC @148996 on x86_64, and compiled the attached test case with
'-m32':
(gdb) start
Breakpoint 1 at 0x80483d9: file gcc-pr40012-test.c, line 24.

Bah, simply not expanding those variables (whose SSA partitions were already)
by clearing TREE_USED on them fixes the problem, but makes those variables
have no debug info at all, as the DECLs then have no DECL_RTL_SET

Also broken on arm-eabi cross. Using gdb and the exact steps as in Comment #0
shows me problem as 0x100.

cfgexpand.c:expand_used_vars() expands and instantiates virtual-stack-vars for
INSNs when it walks the partion map:
for (i = 0; i < SA.map->num_partitions; i++)
{
tree var = partition_to_var (SA.map, i);
--- Comment #4 from dje at gcc dot gnu dot org 2009-06-01 21:49 ---
Local variable debugging is broken for AIX stabs as well.
On AIX, the DECL and the insn contain different offsets from virtual-stack-vars
for the same variable:
(mem/c/i:SI (plus:SI (reg/f:SI 115 virtual-stack-vars)

Revision 146817:
http://gcc.gnu.org/ml/gcc-cvs/2009-04/msg01459.html
is the cause.
