Yukihiro "Matz" Matsumoto 60919807e5 backtrace.c (each_backtrace): make return type to size_t 2024-02-07 17:34:33 +09:00
Yukihiro "Matz" Matsumoto 0a11215452 backtrace.c (packed_backtrace): avoid calling each_backtrace() twice 
Since the length of the backtrace is at most `ciidx + 1` we can avoid
the first call of each_backtrace().
 2024-02-07 17:32:58 +09:00
Yukihiro "Matz" Matsumoto b67cea4442 backtrace.c (pack_backtrace_i): avoid infinite loop; ref #6161 
When irep->refcnt reaches UINT16_MAX, mrb_irep_incref() raises
exception but the function pack_backtrace_i() is called from
mrb_exc_raise() thus causes the infinite loop problem. So this is a
hack-ish workaround by making irep reference to NULL if refcnt reaches
the maximum count. Probably we will address this issue again to make it
better.

dearblue 9543cfa7ee Fixed use-after-free by backtrace object 
The `MRB_TT_BACKTRACE` object has been added for the purpose.

Previously, "use-after-free" could occur because the reference count in `backtrace_location::irep` was not incremented.

fixed #6160
