  I don't know how to read the oom dmesg, but as to the -fmem-report:

... what that's telling us is that there isn't a substantial leak in GCC, as
there's only 7 meg left unreclaimed by GC at the end.  I think we'll have to
wait and see what the debugger tells us; either GCC really is using that much
memory in processing the file, or there's some kind of system or kernel bug
you're running into that is causing a leak in the VMM rather than the application.

  0xFFFFFFFFFFF00000, lol, wut?  It's possible that indicates some sort of
memory corruption going on.  Maybe valgrind can help, do you have that?

    cheers,
