        I haven't heard of any problems with libgc with grsec, but I've never tried myself. I don't think it diddles with the address space much, but it might affect the behavior of some of the nodes in /proc/self/ which libgc uses.
Again, the libgc mailing list is probably the right place to pursue this.
