Core dump (gdb)at /shutdown

[Pietia10]

When you type /shutdown and gdb is on this happens:

Program terminated with signal SIGSEGV, Segmentation fault.

The log does not provide enough information due to being incomplete. Also, I never had this issue myself.

You should ask each thread of the server where it currently is (thread N -> where) and perhaps you will be able to find some more useful information.

[Pietia10]

This bug is in latest trunk for sure.
That didn't helped same trace.

[iryont]

Alright then, please comment following two lines:

https://github.com/opentibia/server/blob/legacy/src/game.cpp#L167
https://github.com/opentibia/server/blob/legacy/src/game.cpp#L168

Basically these two:

g_scheduler.stop();
g_dispatcher.stop();

They shouldn't be in there. The dispatcher won't execute final shutdown call due to closing state.

@Pietia10 did you fix this bug?

[Pietia10]

I'm afraid not.

[diegorodriguesvieira]

@Pietia10 can you help me with an issue?
Ezzz-dev/OTHire#133

This crash rarely happens and I do not know how to solve it

Cheers =)

[Pietia10]

Try to copy CreatureEvent::executeOnKill function also copy this ae3493a from latest legacy.

[diegorodriguesvieira]

Thank you a lot @Pietia10 I will test...

[diegorodriguesvieira]

@Pietia10
Sorry for bothering you so much, but you're my last hope...

Can you help-me with this crash?
Ezzz-dev/OTHire#141

I do not understand very well, but can it be something related to this (checksum)?
https://github.com/opentibia/server/blob/legacy/src/connection.cpp#L349

OTHire does not have this...
