With LAST_UPDATED: "Tue Jul 12 03:25:01 UTC 2005" I still get:

Between LAST_UPDATED "Mon Jul 11 09:23:25 UTC 2005"
and "Mon Jul 11 18:07:42 UTC 2005", I started getting an additional similar
failure for cris-axis-linux-gnu:
...
FAIL: 23_containers/set/explicit_instantiation/3.cc (test for excess errors)
Same ICE.

In addition, the 3.cc test now fails on mmix-knuth-mmixware as well.
Even more, both 2.cc and 3.cc now fail on cris-axis-elf as well.
(No preprocessed source for any of these.)

I'm reducing the testcase from 23310 at the moment.  Trying to produce both
an ice-on-valid and a (smaller) ice-on-invalid (or ice-on-ice, whatever will
come out of it ;)).

the ICE vanishes if -fdump-tree-original, i.e. dumping before the ICE, and
even if dumping after the ICE with f.i. -fdump-tree-vars.  GCAC checking
doesn't complain about anything, so does valgrind.

The issue is that this is very dependent on what is built.

> If not, is there a patch that can get reverted to fix this?

I almost think this is a C++ front-end bug with some GC bug but I cannot prove it.

In some cases 1.cc also fails too with the same ICE.

------- Additional Comments From rguenth at gcc dot gnu dot org  2005-08-25 13:47 -------
Note also that removing any of the (unused) typedef's is causing the failure to
go away, so it looks like something may be overflowing, like a hashtable or an
array.  The symptom is a variable not marked for renaming during/after alias1 pass.

The key seem to be UIDs -- deleting code from the testcase and sticking in enough
typedef int FooXX at the right places makes the ICE stay.

Very weird stuff.
