Looks like it's still PTA:
tree PTA : 255.00 ( 0%) usr 17.25 ( 0%) sys 278.07 ( 0%) wall
28100 kB ( 0%) ggc
(just a snapshot after a few minutes compile)

i'm reopening this bug becasue the fix is not complete.
it does fix the xf86ScanPci.i testcase (time/mem hog) and this is great
$ time gcc xf86ScanPci.i -O1 -c ( 2.2GHz amd64, 1GB ram ).
gcc xf86ScanPci.i -O1 -c 4.10s us

Subject: Re: [4.2 Regression] possible quadratic behaviour.
Testsuite ran on i686-pc-linux-gnu without failures (i've enabled c and

xorg-server now compiles as well.
The patch deserves more testing
