If I change the code from
dw_fde_ref fde = &fde_table[fde_table_in_use - 1];
to
dw_fde_node *fde = fde_table + fde_table_in_use - 1;
I got the same problem.

access_can_touch_variable determines that fde_13->dw_fde_cfi cannot touch
cie_cfi_head; the list of virtual operands of the load thus becomes empty, and
we insert SMT.48 for it.
On *p, we cannot eliminate cie_cfi_he

The problematic piece of .alias5 dump:
p_27 = &fde_13->dw_fde_cfi;
# VUSE ;
D.1763_23 = fde_13->dw_fde_cfi;
if (D.1763_23 != 0B) goto ; else goto ;
# p_18 = PHI ;
:;
# cie_cfi_head_82 = V_MAY_DEF ;
