--- Comment #1 from Jiu Fu Guo <guojiufu at gcc dot gnu.org> ---
The error is raised after ipa “inlining” pass, when doing ggc_collect at stage
2.

At code:
xlimit = ((*xlimit).next);

The value of xlimit becomes 0xa5a5a5a5a5a5a5a5 before crash. 0xa5 may comes
from poison_pages.


If using "-fno-inline" the crash disappears.
