[Bug target/33133] New: [4.3 Regression] ICE in try_ready, at haifa-sched.c:2958 with -O3

[tbm at cyrius dot com]

I'm getting the following ICE at -O3 with current SVN:

(sid)tbm@coconut0:~$ /usr/lib/gcc-snapshot/bin/gcc -c -O3 ncpfs-ncplib.c
ncpfs-ncplib.c: In function 'newpassencrypt':
ncpfs-ncplib.c:46: warning: incompatible implicit declaration of built-in
function 'memcpy'
ncpfs-ncplib.c:48: internal compiler error: in try_ready, at haifa-sched.c:2958
Please submit a full bug report,
...

This worked with 20070811.

Confirmed.  We see this a lot (building xgl, cups, john, xpdf, metacity,
openssl
and more).  And just with -O2 in our cases.

Maxim was testing a patch for it but I'm not quite sure what happened to it.
