Well, if you're running your favourite glib application and it seems to be broken with the output like: (...) *** glibc detected *** free(): invalid pointer: 0x08ced388 ***
It's probably due to the new glib (GSlice) memory allocator[0], but it's an application bug. Please first check if it's really glib related[1]. There's a workaround that is run the application as follows: $ G_SLICE=always-malloc application FYI, evolution seems to be affected and it was already fixed upstream. Sebastian Bacher has a patch to galculator too. If you hit this bug in other random application, please open a bug against the application and feel free to cc: me. I'll try keep track of these bugs with usertags.
