added - the missing 'free(org_dup)' to patch (memory-leak) implement until the 'real' bug is found

however - the problem has to be fixed for this and all other events this may occur as well, or we'll run into errors we can't handle without massive problems
e.g. if a plugin fails - the hub will crash
...your fixes for the plugins are great eric :)

char * or gstring must be free. I suspect something inside GLUS_SEND_TO_A_NICK to release the allocated memory too early. IMHO, the problem should come from perl support. I think when perl functions return, they free the memory. If there is no other plugins (perl/python or plugin), everything works fine but if a plugin uses this memory later... boom.

if freeing is impossible may it would be better to use an GString instead...

at least this is working stable in my hub with 140 users
I encountered not 1 error since I changed to this version.
before the hub crashed when activating the +slots command in the plugin

org_dup is a char no gstring - but put an free later on if you like ;)

you should have a memory leak because org_dup memory is not released no ?

maybe other events have to be checked if such a fix has to be implemented there too.

The usage of the GString org after using the GLUS_SEND_TO_A_NICK doesn't seem to be 100% reliable.
I encountered around 10 of 1000 invalid $SR-results sent to the event handler inside an 100users hub.
...this way it seems to be stable
