[Bug other/17437] New: obscure GC problem

[Graham Stott]

Steven,

FWIW it doesn't fail on a x86-ia64 cross using normal -O2 opts

But I could trigger a failure, but not your failure using  -O3 -fno-unit-at_a-time

t.i:16476: error: Inlined_to pointer is wrong
detect_webs_set_in_cond_jump/314: (inline copy in build_i_graph/312) 54 insns tree inlinable
