Answerscripts.so makes pidgin crash when startup

[baongoc124]

I'm trying answerscripts with Pidgin 2.7.11 and cannot make it to run. Plugin seems to make Pidgin crash. Here's backtrace: http://pastebin.com/57pd14SV

For more info: Commenting line "setenv(ENV_PREFIX "L_AGENT_VERSION", (char *) purple_core_get_version(), 1); //Version of client" from init_plugin function fixes crashing problem.

try latest git version pls :)

[baongoc124]

Still crash with latest git version. Commenting setenv line make it work again.

[Harvie]

fuck :)

Please let me know what output you will se in console with this debug line:
putchar('['); puts((char *) core_version); putchar(']'); //Debug
setenv(ENV_PREFIX "L_AGENT_VERSION", (char *) core_version, 1); //Version of client

and you can also try this:
setenv(ENV_PREFIX "L_AGENT_VERSION", (const char *) core_version, 1); //Version of client

BTW what operation system (os, [kernel, distro,] version) are you using?

[baongoc124]

Here it is http://pastebin.com/4MBWa9WM . I'm using ArchLinux kernel 2.6.38.4, Pidgin 2.7.11.
And adding const to char* doesn't help.

Sorry, here it is http://paste2.org/p/1417336 . I'm using the same Pidgin version but on 64bit.

[Harvie]

It seems to me like some bug in 64b pidgin... I probably returns incorrect address to version string. (It points somewhere else instead which causes SEGV when i try to read string from that address. Can you also try to build pidgin from ABS using latest GCC with all optimalizations disabled?

(I don't have any 64b machine, so i can't make those experiments on myself)

[baongoc124]

Recompiled and still crashed. These are arguments to ./configure http://paste2.org/p/1417381

[Harvie]

I can reccomend you to fill upstream libpurple bug at http://developer.pidgin.im/
and ask why purple_core_get_version() is returning crap on 64b...

[Harvie]

BTW if you will do so, please post here URL of that issue so we can give votes to it and watch status.

[Harvie]

Still issue with latest pidgin? BTW pidgin 2.8 seems buggy to me (but not related to this issue...)

[Mates]

Issue still persists on Pidgin 2.10.1, x86_64. Commenting both of these lines helped me.

setenv(ENV_PREFIX "L_AGENT", (char *) core_ui, 1);  //ID of IM client used with answerscripts
setenv(ENV_PREFIX "L_AGENT_VERSION", (char *) core_version, 1); //Version of client

also, a little off-topic, scripts don't work within multichats, can anything be done about that?

[Harvie]

Well as workaround i've disabled L_AGENT on 64b.

BTW can you try to move those lines:

    const char * core_ui = purple_core_get_ui() != 0 ? (const char *) purple_core_get_ui() : "";
    const char * core_version = purple_core_get_version() != 0 ? (const char *) purple_core_get_version() : "";
    setenv(ENV_PREFIX "L_AGENT", (char *) core_ui, 1);  //ID of IM client used with answerscripts
    setenv(ENV_PREFIX "L_AGENT_VERSION", (char *) core_version, 1); //Version of client

Just after this line (where all other setenvs are):

setenv(ENV_PREFIX "L_STATUS_MSG", status_msg, 1); //status message set by local user

i think it may help... but i am not sure... let me know please.
