Error on mrb_str_cat function (str_buf_cat)

[rmalizia44]

Everytime I create a Ruby String and call mrb_str_cat it gives a Segmentation Fault (using Linux Ubuntu).

Example Code:

mrb_value new_obj = mrb_obj_new(mrb, mrb->string_class, 0, NULL);
const char* test_str = "test";
new_obj = mrb_str_cat(mrb, new_obj, test_str, 4);

I reverted str_buf_cat master to 1.2.0 on "string.c" and the Segmentation Fault stopped.

Just a guess, but that sounds like new_obj is not fully initialized. Perhaps try using mrb_str_new_lit() to initialize it.

Yes, use mrb_str_new* to create string objects.

mrb_str_new worked! Thanks very much!
