invalid pointer starting rolauncher - both 32 & 64 bit

[Thelfin]

Hi, I've got very similar errors trying to run rolauncher in both 32-bit and 64-bit forms. I'm running Source Mage GNU/Linux, and I use a pure 64-bit environment for the 64-bit, and a pure 32-bit environment in a chroot for 32-bit. Here is the error output for each environment, with the memory maps removed due to length. It will be seen they are remarkably similar.

64-bit

4 lines in the errors from the 32-bit version are from a bad Gtk theme, so I suppose Gtk is being initialised. Gtk version is 2.12.2 in 64-bit and 2.12.3 in 32-bit.

I don't suppose OpenGL has anything to do with it at that stage, but I do have OpenGL games working very well in both 32- and 64-bit environments, open source in the 64-bit and closed source (Second Life) in the 32-bit.

This is a well known bug of the Regnum client. Lots of pointers are free() more than once (which is a bad programming way of doing things). You should try a to use the environnement variable MALLOC_CHECK_ and turn it to 1 before starting RO.

export MALLOC_CHECK_=0
./rolauncher

Ah, thank you, that worked in both environments.

Had to run it a couple times but it worked!
