gEDA-bug: [Bug 732326] [NEW] gschem segfaults on recoursive loop

[KaiMartin <732326@xxxxxxxxxxxxxxxxxx>]

Public bug reported:

This bug was reported on gmane.comp.cad.geda.user by Vladimir Zhbanov:

gschem segfaults when confronted with a symbol that contains itself.
To reproduce: 
1) copy a symbol foobar.sym to the current working directory
2) open the copied symbol in gschem
3) type [i] and choose the local symbol foobar.sym in the chooser
4) add foobar.sym to the canvas
5) save (as foobar. sym) and close gschem
6) open gschem on foobar.sym
--> immediate segfault.

Suggestion: gschem should check for recursive loops when opening a
schematic.
