Forgot to provide the actual failure mode:
unwind-ia64_s.o(.text+0x30b2): In function `uw_frame_state_for':
../.././../gcc-4.5-20091112/libgcc/../gcc/config/ia64/unwind-ia64.c:1788:
undefined reference to `_Unwind_FindTa
It turns out that bug #40959 actually is only one of two regressions
that breaks bootstrap on FreeBSD/ia64. This is the other case.

Is there anything else that any of us can do (dumps, testcases, etc) to help
get this bug tracked down and fixed? If access to a native SPE system would
help I can set you up with remote access credentials to one of ou

As explained at http://gcc.gnu.org/ml/fortran/2010-09/msg00120.html the
transpose change committed at
http://gcc.gnu.org/viewcvs?view=revision&revision=164205 introduces unnecessary

I'm traveling. Note, I don't understand how you are addressing my concerns,
thus whatever results you get from the testsuite, make sure we are not
regressing on the situation I outlined, thus write a new testc

I'm unsure exactly how to get the preprocessed output required...
I ran:

/home/suigintou/include -I /home/suigintou/usr/include -std=gnu9
Be nice, this is my first attempt at filing a bug report ever :)

Run the full testsuite, and you will see. In general, if you simply do fseek(0,
cur) and then start writing, when eventually you have to flush you need the
actual logical position in the file - the last fseek(

I think altivec should disabled with "gcc version 4.0.1 (Apple Inc. build

Revision 164163 fixes the bootstrap failure as well as the problem with
dsymutil reported by Jack Howarth in
http://gcc.gnu.org/ml/gcc-patches/2010-09/msg00886.html .
Closing as fixed.
