------- Comment #2 from suckfish at ihug dot co dot nz 2008-10-11 21:35 -------
Using '-da' it looks like the 'combine' pass is the culprit:
$ pidof cc1
6410
$ ls -l /proc/6410/fd
... 4 -> ... slow.c.162r.combine
$ ls -s slow.c.162r.combine
0 slow.c.162r.combine
[is there an easier way to get cc1 to tell me what pass it's running when?]
