[fixed] 3.8.0-beta1: SegF in type_instances/unit.cpp:2466

[tomreyn]

I was a client (standard 3.8.0 beta1) on a game filux hosted on his (patched/modified) SVN build, and while the game continued for Filux and Nig (a Windows client), I ran into a SegF:

So much, so little. And no DMP file.

But a core file. And this is the backtrace:

Does it help?

[filux]

My version is/was of course latest svn (r.4528) and I didn't patched anything related with game's engine.

[softcoder]

Is this defect reproducible? Are there specific steps that can be followed to trigger it?

[tomreyn]

It was the first time I ever ran into this one, and I play somewhat often, so if it is reproducible then it's very difficult to do so, and I don't know how to do it.

[softcoder]

This is likely impossible to reproduce since the latest updates in snv.

[tomreyn]

So let's consider it [fixed] (unless it occurs again in which case this report should be referenced or reopened).
