#623 Crash when hatching

[Amit Chaudhuri]

RS_EntityContainer::ignoredOnModification() const (this=0x0) at lib/engine/rs_entitycontainer.cpp:1908

bug.dxf is a simple plan of a wall with some tiles. I create some times and then hatch them. I find the process unstable, with frequent crashes, particularly if (maybe only if) I create several adjacent tiles, select them (entity select with mouse to point and select each) and then apply the hatch (with preview enabled).

gdb.txt shows a logging session in gdb starting with a backtrace. The source of the crash is pretty clear. An upstream function returns a nullptr because it has no parent. The coding pattern looks to be repeated quite widely across different objects in ::rtti().

Latest master. Linux Ubuntu 22.04.

Adding sample file.

Hi Amit,

Have you tested the latest development version?

I have been testing the dxf file you attached, and could not reproduce the issue.

For the latest source and pre-releases, please visit our page at github. We don't use this site often nowadays.
