First off, I didn't when I ran my regular
bootstrap + libjava_check cycle. That's because
I use "--disable-checking".

Second, it's most likely caused by Nathan's assertifying
patch to gcc/p*.c:

  http://gcc.gnu.org/ml/gcc-patches/2005-04/msg00227.html

Note that the "#ifdef ENABLE_CHECKING" guard
in postreload-gcse.c (around line #741) was
*misspelt* before:

  - #ifdef ENABLE_CHEKCING

and was thus never being executed before.
