but without opts it is ok. Starts failing at -O1.
Comment 3 Benjamin Kosnik 2008-07-15 16:38:27 UTC 
Configured with --disable-checking.
Comment 4 Benjamin Kosnik 2008-07-15 17:13:26 UTC 
Workaround is to use --enable-checking=release, which works. Thanks Andrew Pinsky!! gcc_assert issues?

Comment 6 Richard Biener 2008-07-15 21:47:45 UTC 
works for me
Comment 7 Andrew Pinski 2008-08-11 00:46:16 UTC 
Does this work now?
Comment 8 Richard Biener 2008-08-22 14:44:07 UTC 
Still works for me.  Closing due to lack of response from reporter.
