--- Comment #3 from Robert Clausecker <fuz at fuz dot su> ---
I checked this again on a computer with more RAM and compilation does indeed
terminate
after 23 minutes. On the original machine, the compiler most likely swapped a
lot contrary
to my original report in which I didn't let the compiler run long enough to
start swapping.

Can someone mark this as CONFIRMED?
