have appeared on mainline on i686-pc-linux-gnu (and from gcc-testresults it
seems some other platforms too) between 20050517 and 20050518.  All seem to be
of the form "internal compiler error: tree check: expected ssa_name, have
var_decl in verify_ssa, at tree-ssa.c:750".

Also new today on i686-pc-linux:
FAIL: gfortran.dg/vect/vect-5.f90  -O  (test for excess errors)
I can't confirm the C failures because I only run the Fortran testsuite.

The following failures appeared on ia64-hpux between 20050517 and 20050519 (on
20050518 there was a bootstrap failure) and appear to be the same bug.

These failures should have been fixed after this: 
http://gcc.gnu.org/ml/gcc-patches/2005-05/msg02756.html

With the fix above I no longer see these testcase failures on powerpc-apple-
darwin, but the ICEs reported in PR21155 and PR21789 still remain (these PRs do 
look related, but the fix above apparently did not cover these cases).
