--- Comment #10 from Tobias Burnus <burnus at gcc dot gnu.org> --- The callee is: <var_decl 0x3fffb7f80630 c_aptr type <pointer_type 0x3fffb5ac0fc0 type <void_type 0x3fffb5ac0f18 void VOID align:8 warn_if_not_align:0 symtab:0 alias-set -1 canonical-type 0x3fffb5ac0f18 pointer_to_this <pointer_type 0x3fffb5ac0fc0>> and the hidden argument (_c_aptr) is: <integer_cst 0x3fffb5a01218 type <boolean_type 0x3fffb5ac0b28 logical(kind=1)> constant 1> which both look fine.
