New segfault (RPi2)

[Jammet]

Ah, I see. I don't have one, I'm afraid. ^^' Thanks, however.

I've encountered a new segfault.

2 players were connected, and walking their freshly tamed dogs, and there was plenty of fighting with monsters going on.

Wow that was fast! We do take out these dogs for a spin, now that they're helping .

You should probably wait for #2878 to be merged.

Here is another new segfault. I do not know what it has been caused by.

Code:

[Seadragon91]

This 2 lines looks interesting

Code:

terminate called after throwing an instance of 'Json::LogicError'
what(): Type is not convertible to string

[xoft]

Interesting, but without a stacktrace, there's very little hope of actually finding where the problem occurred.

[tigerw]

It sounds like it may be coming from calls to Json::Value::asString - there are only a few places where that's called.
