#0  do_structure_copy (lhsop=Variable "lhsop" is not available.
) at tree-ssa-structalias.c:2320
#1  0x000000000086d932 in find_func_aliases (t=0x2a95bc6cd0, ai=Variable "ai" is

in frame 1 we have

(gdb) call debug_generic_expr(t)
#   SFT.93D.2964_74 = V_MAY_DEF <SFT.93D.2964_71>;
#   SFT.94D.2965_75 = V_MAY_DEF <SFT.94D.2965_72>;
#   VUSE <SFT.83D.2954_25>;
#   VUSE <SFT.84D.2955_26>;
D.2920.D.2564.functor_D.2525 = D.2460

and we pass (D.2920.D.2564.functor_D.2525, D.2460) to do_structure_copy.

This looks like a dup of ... (searching)
