Re: Crash on exit

[Andrei Zmievski <andrei ispi net>]

Ok, more interesting information on this. Owen mentioned that it's
probably related to the way the .so file is loaded/unloaded.  While
testing this today again, I happened to compile PHP with libs from
gtk-config --libs and the whole thing worked. So, when it's linked with
GTK+ libs - it loads .so file just fine and there is no crash on exit.
When it's not linked with GTK+ libs, the below mentioned crash happens.
Obviously, I can't require people to link their PHP with GTK+ libs if my
module is going to be distributed separately... Any ideas?
