Hi Anton,

I am currently affected by this bug. I am using an older release (but
not too old) andI updated the code following your fix in r2880. The bug
still occurs though but I have have not rerun the test. I reload the old
test using the code I recompiled after the change, I remove the bodies I
do not need anymore, save the test and then reload it again (but the
crash occurs). Do I perhaps need to rerun the test for the change to be
effected?

Also, could you explain in words your fix in the code?

Thank you.
Chiara

Title:
  Saving, loading simulation with erased bodies crash.

Status in Yet Another Dynamic Engine:
  Fix Released

Bug description:
  Here is the bug :

  - launch yade (for example without any script)
  - add a sphere : O.bodies.append(utils.sphere((0.2,0.2,0.2),0.006))
  - delete it : O.bodies.erase(0)
  - save yade's universe : O.save("./test")
  - quit yade
  - launch yade
  - load the file : O.load("./test")
  ->segmentation fault

  I think it's because when you erase something the size of O.bodies (etc...) doesn't change and now contains an empty value. (the c++ array may not be dynamic ?)
  So when the O.load() function is called, yade try to load a non-existant body ?

  Maybe this can be fixed by changing the load() method ?

  I joined the debug output.
