Hi microm,

I can not reproduce the crash with 2.0.8 or 2.0 HEAD.

can you share a dxf with specific and explicit steps?

We did fix a undo related crash after 2.0.8:

After save-load operations error not reproduced.

More easy way to crash.
Draw normal line. Draw two lines with parallel line tool. Undo one last line, and draw it again.
Crashes on windows and linux.
Linux version 2.0.8 from official repository.
Windows version 2.0.8 from official site.

This is the bug fixed by the mentioned commit

Trying build 2.0.8-50-g194c675
Problem is gone.

But have another one :)

draw line(1) with tool line
select tool "parallel line", plaсe pointer near line(1) that there was dotted line.
do not move mouse!
press ctrl+z, both lines vanish.
then mouseclick crash librecad.

Thanks a lot!

A quick fix is in master and 2.0 branch:

to avoid using entities deleted by "undo", the undo action will stop all suspended actions to avoid crashes.
