Lots of 'cc' crashes with today's -current

Hi folks,

I just upgraded my -CURRENT machine and I also upgrade my ports
after a system uprade. Now lots of port-builds failed now because
cc (but not exclusive) died with coredump.

Here more details:

atrbg11:~>uname -a

/etc/make.conf contains:
[..]
CFLAGS= -O -pipe
[..]

for optimization, nothing fancy.

Ports which caused cc to crash:

x11/XFree86-4-clients
devel/libbonobo

BUT, this is not reproducable. I built the libbonobo Port a second
time, and this time it worked. I tend to rule out hardware issues
for now, since the hardware has not changed since nearly a year,
but the system did change right before.

Build/Installworld etc went flawless.

Maybe some ACPI CPU frequency tuning thing? 
Were there changes to the system gcc?

It's really strange... :(

Best regards,
 Daniel
