Cannot compile klee file if typename equals variable name

[IDKWNTCMF]

Description If a type name equals variable name then klee file cannot be compiled in some cases.

Example

typedef struct {
    int fld;
} str;

int cas(str *str, int val, int new_val) {
    if (str && str->fld == val) {
        str->fld = new_val;
        return 1;
    }
    return 0;
}

To Reproduce Steps to reproduce the behavior:

1. Copy the example above to your project
2. Try to generate tests for cas function

Expected behavior Tests are supposed to be generated.

Actual behavior Couldn't compile klee file.
