mass crash - spring 87.0

[jamerlan]

We had a battle 3 vs 3 and all (except 2 players) crashed at the same time.
I watched demo and it crashes too with the same error.

gdb dump (from demo watching):

infolog.txt (from demo watching) and demo are attached.

You can reproduce this bug by watching demo till the end (32+ minute).

to me it looks like a bad_alloc was caugh in an exception catch block, that should actually not have caught it. due to this, the required stack-trace information was lost, and is not visible in the GDB output.

it might be related to this commit:

hoijui, could you please reproduce this crash yourself? using attached demo.

I am complete noob in gdb so I can miss some critical info. Maybe you can even debug this with debugger? I mean via breakpoint in ide.

I think that this is very important bug. Mass crash after 30 minute game - all players were disappointed and left battleroom.

The error was thrown in a non-mainthread thread. Also that gdb wasn't able to create is a known issue (we should add a gdb detection code (or copy it from watchdog) and rethrow the exception in such cases).
Also I am unsure if Spring doesn't print a stacktrace in this case itself (the infolog.txt pasted here is cut, either type a `sync` in the bash next time or copy the bash output)

jK, I attached with gdb to spring after crash. Next time I will do "sync" but I am sure that this will not help.

Please reproduce this bug using atached demo. You will be able to get all info you need.
