Trying to solve a crasher in editeng unit test

[Kohei Yoshida]

Hey there,

I'm trying to set up a new unit test for the edit engine core, but
struggling with one crasher.

On the latest master, when you open

editeng/qa/unit/core-test.cxx

and uncomment line 132 and re-run make check, it fails with segmentation
fault.  The backtrace is attached.

Anyone have any clue what could be the cause?  Anyone seen anything
similar in the past?

Thanks,

Kohei
