Thank you for your report.

First, please file a bug about this via "M-x report-emacs-bug RET".

Second, please show the value of it->current in frame #7 (inside
next_overlay_string).

Third, could you please try the latest development code, and possibly
compile without optimizations?  Several bugs in this area were fixed
since 24.2 was released, so perhaps this is one of them.
