I just tried to compile the Linux kernel 2.6.30
with the GNU gcc version 4.5 snapshot 20090611.

The compiler said

drivers/usb/host/ehci-hcd.c:1177:1: error: non-register as LHS of unary
operation
# .MEM_144 = VDEF <.MEM_130>
qh_11(D)->qh_next.qh = (struct ehci_qh *) here$ptr_140;

drivers/usb/host/ehci-hcd.c:1177:1: internal compiler error: verify_stmts
failed
Please submit a full bug report,
with preprocessed source if appropriate.
See <http://gcc.gnu.org/bugs.html> for instructions.

Preprocessed source code attached. Flag -O2 required.
