OK, but please note that the callee_type and caller_type have
different sizes here:
(gdb) pt callee_type
<integer_type 0x7ffff76bc5e8 int public SI
size <integer_cst 0x7ffff76a3cd8 type <integer_type 0x7ffff76bc0a8
bitsizetype> constant 32>...
(gdb) pt caller_type
<record_type 0x7ffff77c7dc8 str_t type_0 BLK
size <integer_cst 0x7ffff76c11b0 type <integer_type 0x7ffff76bc0a8
bitsizetype> constant 96>...
...so you are creating a size-mismatched V_C_E. Don't you want to use
force_value_to_type instead?
