Is this -fdump-all-all version specific? Doesn't work on 4.1.1:
$ g++ -fdump-all-all allocation.cpp
cc1plus: error: unrecognized command line option "-fdump-all-all"

No, I goofed. I must've dreamed the -all-all switch. You have to use -fdump-tree-XXXX for GIMPLE dumps and -fdump-rtl-XXXX for RTL dumps. It's also possible that -fdump-rtl doesn't work on the 4.1 series (I don't recall when -fdump-rtl was introduced, sorry).

Check the invocation sections in the GCC 4.1 manual. Grep for fdump-.
