I tried this and still can't reproduce it with the standalone testcase.
GNU C version 3.5-tree-ssa 20040301 (merged 20040211) (i686-pc-linux-gnu)
compiled by GNU C version 3.5-tree-ssa 20040301 (merged 20040211).
GGC heuristics: --param ggc-min-expand=30 --param ggc-min-heapsize=4096
Output is the same at -O0, -O1, -O2, and -O3:
---------------------------------------------------------------
__alloc_bootmem_core(0xbffff250, 00001000, 00001000, 00000000)
bm2, found: 0.
0/1
reserve 1 bits, starting at 0.
0/1: 0
=> (nil).
---------------------------------------------------------------
The program always exits with code 0.
I'll take a look at the original test case.
