Confirmed.
An intermediate partition is completely empty (ltrans_partitions[2], after
lto_balanced_map (), out of 7 partitions in total). Sorting moves that
empty partition last.
We do seem to allow a single empty partition (probably for an empty CU):
gcc_assert (cgraph_node_set_nonempty_p (set)
|| varpool_node_set_nonempty_p (vset) || !i);
so we could change !i for i == n_sets-1, but I suppose we could arrive
with multiple empty partitions here as well.
Honza, why do we even care to assert the above if we handle empty
partitions just fine (in case of !i)? It looks like some partitioning
sanity check to me, not something we should assert on.

The reason was that empty partition imply overhead and there is no need for
that, so I would preffer partitioning algs to never create the empty parts
(there was various issues with partitioning that lead to them).
But for release branch, dropping the assert is just fine.

--- Comment #8 from vincenzo Innocente <vincenzo.innocente at cern dot ch> 2011-04-04 13:22:26 UTC ---
I downloaded and installed
gcc version 4.6.1 20110401
as I issued a "make" in the same area where I had the ICE in
lto_wpa_write_files
I got
lto1: internal compiler error: in lto_reissue_options, at lto-opts.c:418.
Once "make clean" and rebuild from scratch things when fine.
So it looks to me that the new version cannot use previously produced object
files
Besides this minor point (I had only to wait 45 minutes using 8 cpus to have my
full application to build)
I confim that LATEST/4.6.1 solves the issue

The problem should be fixed on mainline now. Concerning comment #8, the problem
is that LTO files needs to be rebuild after every compiler update. Official
release will bump up LTO file version number and diagnoze the issue as version
mismatch. For sources pulled out of SVN you get this kind of errors.
