--- Comment #1 from Richard Guenther <rguenth at gcc dot gnu.org> 2012-01-05 15:15:46 UTC ---
All C ICEs are due to us not supporting the 'optimization_node' trees
(PR50490).

The C++ ICEs are all TM and

/space/rguenther/src/svn/trunk/gcc/testsuite/g++.dg/tm/pr45940-3.C:69:1:
internal compiler error: in write_symbol, at lto-streamer-out.c:1333^M


The gfortran ICEs are all GIMPLE IL verification ICEs with regarding to
structure compatibility (thus, TYPE_CANONICAL mismatches).  Two kinds
can be observed:

/space/rguenther/src/svn/trunk/gcc/testsuite/gfortran.dg/alloc_comp_assign_2.f90:7:0:
error: non-trivial conversion at assignment^M
struct array1_integer(kind=4)^M
struct array1_integer(kind=4)^M
a.68.i = parm.70;^M

and

/space/rguenther/src/svn/trunk/gcc/testsuite/gfortran.dg/class_array_7.f03: In
function 'main':^M
/space/rguenther/src/svn/trunk/gcc/testsuite/gfortran.dg/class_array_7.f03:49:0:
internal compiler error: in fold_convert_loc, at fold-const.c:2016^M

The single Ada ICE is

/space/rguenther/src/svn/trunk/gcc/testsuite/gnat.dg/aggr1.adb: In function
'aggr1':^M
/space/rguenther/src/svn/trunk/gcc/testsuite/gnat.dg/aggr1.adb:3:1: error: type
mismatch in array reference^M
struct aggr1__graph_table_t___PAD^M
^M
struct aggr1__graph_table_t___PAD^M
^M
VIEW_CONVERT_EXPR<struct aggr1__T30b>(graph_table[1]{lb: 1 sz: 59956}.F).active
= 0;^M
^M

and two more similar ones.
