Hi Rob.  This is LP: #623945 'ICE using va_list with -g
-femit-struct-debug-baseonly' which was fixed in the recently released
Linaro GCC 4.5-2010.11. See:
 https://bugs.launchpad.net/gcc-linaro/+bug/623945
for more information.  Note that Linaro GCC 4.4 is in maintenance and
doesn't include the fix.

Out of interest, where do you pick up the binary build of your
toolchain from?  Self built?  From Ubuntu?  Some other way?  I'm
wondering about the best way you can pick up this fix.
