Unfortunately I can't do anything with that trace, since the crash is happening inside MariaDB itself.

In response to Lummox JR
Do you have any idea what I can try to do?
Mar 29 2018, 7:39 pm
Offhand I can't think of anything at the moment, except maybe try looking at the query being run to see if there's anything about that in particular that could be a problem.

Also I would say the multiple world/New() calls are concerning; that means you've overridden the proc in multiple places instead of just doing it in one place, which is a lot more reliable. While I don't think a timing issue is in play, it's just not a good idea to split up your procs that way.

If you know which exact build of MariaDB you're using, it's possible that there's info about a crash at those offset positions floating around online.

In response to Lummox JR
I using this lib and the recommended file. http://www.byond.com/developer/Dantom/DB?tab=index

The operating system is 64 bits, but I can host the game normally because I've used the commands. I tried other .so files but none of them worked.
Mar 29 2018, 8:25 pm
We need to know the exact and full version number of mariadb you have installed.
Mar 29 2018, 8:31 pm
In response to MrStonedOne
I tried more than one version and more than 5 dirs (like xirre said in the Discussion of the lib )

2.0.0
2.0.16
2.3.5
debian and linux version
etc
Mar 29 2018, 9:02 pm
I mean for the back trace(s) you pasted above. what version(s) of mariadb were you using there. Lummox can go cross reference what exactly maria-db was doing based on the offset in the stack trace, but he has to have the exact same version that the backtrace was generated from as the offsets change between versions.
Mar 29 2018, 9:06 pm
In response to MrStonedOne
Using 2.0.0 in /usr/lib the result is the second trace, the unique trace that appears to have some interaction with DreamDaemon.

Er, it appears you copied that content from a site that uses relative URLs, and as a result none of those links work nor do any included images. You'll want to edit that. [edit: Looks like you just did.]

Although I don't know that it throws any useful light on this issue anyway. I'm not even sure what the table is for.

I did some quick Googling last night of the offsets that came up in your crash, but I found nothing. Ultimately if MariaDB is crashing, it's because it's being passed bad data or running in an environment it shouldn't. Since other games use it with no trouble, I don't think the bad data is coming from BYOND.

As a non-Linux guy I can't answer this question, but is it possible that /usr/lib isn't the right place to put this library since it's 32-bit? AFAIK, SS13 builds just leave it in the same directory as the .dmb. Maybe your system is trying to load it differently because of its location, and that could account for the trouble?

In response to Lummox JR
I tried more than 5 different locations, including the same directory + -trusted. When the file is in /usr/lib the error changes, showing that there is some interaction, even if it fails.

Similar problems:

apt-get install libmysqlclient-dev:i386
don't solved the problem, I'd installed the i386 architecture. (change de backtrace too)
libmysqlclient.so 0x1a8b0, 0x1a8e2 (mysql_send_query)


http://www.byond.com/forum/?post=1878002
The /usr/lib32 folder did not exist, even creating and putting the file there did not happen.

http://www.byond.com/forum/?post=117576#comment16921941
Same to /lib

Ins't possible include and load natively in the next update? Already exist the secret proc _dm_db_execute()

• The library is located in the BYOND user bin/ folder (~/.byond/bin on unix, typically "My Documents/BYOND/bin/" on windows). This is intended to allow the user to install permanently "trusted" libraries. -OR-
• The server is run in -trusted mode. -OR-
• The server grants permission to access the DLL at runtime, through a prompt query.
