(Doi!) Forgot it was executing initial rc scripts. Turned on -x since last statement seems pretty mundane. Also 6 statements after where it claimed it crashed, is a custom function for printing pwd for the prompt.
I've tried with different compile ops (optim vs. dbg). with builtin readline and included readline with bash-malloc set, and unset.. This isn't blocking anything, so no time pressure.

You could start with the actual command that's dumping core (something in one of your startup files) and your locale. A backtrace from the core dump would help, too, but not as much.
attach is output from bash -x .. last line displayed in that was line#288. Starting from line 288, about 4 statements down are the defines for a "short"-pwd (spwd)for my prompt.
It might have been in that function -- as it seems it is the
only thing of any complexity. I skipped blank lines and some
comments. Line number is line after the line# comment.
