Unfortunately, there are some stuff like this:

 <addr_expr 0x7ffff708f680
    type <pointer_type 0x7ffff7094690
        type <array_type 0x7ffff7094540 type <integer_type 0x7ffff6ef3dc8 char>
            size <integer_cst 0x7ffff708f540 constant 280>
            unit size <integer_cst 0x7ffff708f620 constant 35>
            align 8 symtab 0 alias set -1 canonical type 0x7ffff7094540 domain
<integer_type 0x7ffff70943f0>
            pointer_to_this <pointer_type 0x7ffff7094690>>
        unsigned DI
        size <integer_cst 0x7ffff6ecddc0 constant 64>
        unit size <integer_cst 0x7ffff6ecdde0 constant 8>
        align 64 symtab 0 alias set -1 canonical type 0x7ffff7094690>
    readonly constant
    arg 0 <string_cst 0x7ffff7059038 type <array_type 0x7ffff7094540>
        readonly constant static "%s:%d: %s: Assertion '%s' failed.\012\000">>

so we cannot assert that the format_expr has no unknown location.
