Ugh. Basically the way we treat SCC members during type merging isn't correct.
I have a patch.

PR lto/46648
* gimple.c (gtc_visit): Do not return true for members of an
SCC still being processed but the current lattice value of
the member. Treat SCC members comparison state as lattice,
starting at equal, eventually dropping to unequal.
(gimple_types_compatible_p_1): Likewise.
* gcc.dg/lto/20101125-1_0.c: New testcase.
* gcc.dg/lto/20101125-1_1.c: Likewise.
Added:
