Reorder members in `struct backtrace_location`
`sizeof(struct backtrace_location)` is 24 bytes -> 16 bytes in LP64
data model etc.
struct backtrace_location {
int lineno;
- const char *filename;
mrb_sym method_id;
+ const char *filename;
};
typedef void (*each_backtrace_func)(mrb_state*, struct backtrace_location*, void*);
