Jim, David, can one of you look at this, and maybe revert the patch
for PR13158 because it causes this regression?
Reverting the patch doesn't sound like a good idea, because

Without a test case, nobody can give this bug a proper look. Can you
provide an example of how this fails for you?
Sorry, that was sloppy of me. I'll attach a minimal test-case

What gcc are you using also since the version you filed in as unkown?
$ gcc -v
Reading specs from /usr/lib64/gcc-lib/x86_64-suse-linux/3.3.3/specs

when gcc builds crtbegin/crtend, we do pass -fno-exceptions but in the
backend, we set
flag_asynchronous_unwind_tables to 1 if we have not set it yet but we don't
touch

Well if _init/_fini is created by the linker then isn't this a linker bug
which should generated the unwind
info?
I don't really care which way it goes.

Since I don't have access to an IA64 machine could you submit/regtest the
patch which removes the
aligned_p test?
Just removing the aligned_p won't do the trick. It's also

This is a lot more failures than we should have. I didn't have any luck

Perhaps I should have read your message closer. I get timeouts for this
testcase also. However, it bootstraps fine, and the total number of
unexpected gcc failures is only 45

I've now checked the patch into mainline.
Thanks!
Adding the patch to gcc-3.4 requires that it be a regression. This doesn't
seem to qualify according to a strict

You didn't say what kind of problems you ran into with gcc mainline.
The compiler seemed to get stuck in an apparent endless loop. make check
quickly resulted in timeout failures

Argh, I reran make check-g++ with the original (unpatched) GCC and am now
seeing 3 unexpected failures (when the exact same compiler produced 0 failures
yesterday). From what I can

OK, I tried this patch on the CVS gcc-3_4_branch (the 4.0 branch didn't work at
all for me, even in it's pristine version). As you said, the patch does fix the
bug I reported. In addition, the test-suites
