If this is a GC problem, I should post the output of gcc -v: 
 
deal.II/deal.II> ../../../gcc-install/bin/c++ -c -O2 -funroll-loops fe_system.ii -v

GNU C++ version 3.4 20030903 (experimental) (i686-pc-linux-gnu) 
        compiled by GNU C version 3.4 20030903 (experimental). 
GGC heuristics: --param ggc-min-expand=55 --param ggc-min-heapsize=48139 
 
And sure enough, on that other machine the ggc parameters are different. If I set them 
to the same values, I can reproduce the crash there, too.
