Thanks for your reply, Eli.

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

When? :)
(after the crash,= the process is gone, so can't M-x anything; before the crash, there= 9;s nothing interesting to report :))
In case it's interesting, appended the info from r-e-b (from an em= acs -Q instance) to the bottom of this email.

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 compi= le without optimizations?

Will do & rep= ort back in a few days (or sooner, if the bug recurs in HEAD).=A0
