is fixed.  I don't see

FAIL: ext/pb_ds/example/basic_set.cc (test for excess errors)
FAIL: ext/pb_ds/example/basic_set.cc (test for excess errors)

what are the excess errors?
Comment 2 H.J. Lu 2009-03-28 18:29:10 UTC 
I got

g++: Internal error: Killed (program cc1plus)^M
Please submit a full bug report.^M
See <http://gcc.gnu.org/bugs.html> for instructions.^M

FAIL: ext/pb_ds/example/basic_set.cc (test for excess errors)

My machine has 4GB RAM and 2GB swap.

This is introduced between revision 145183 and 145186. One of
revisions 145184/145185 may be the cause.
Comment 4 Richard Biener 2009-03-28 21:31:41 UTC 
I still do not see this (my machine also has 4gb ram).
Comment 5 H.J. Lu 2009-03-28 21:59:24 UTC 
All fixed as of revision 145202:
