I upgraded my ubuntu to 11.04 and started have compilation
and test failures. With the supplied gcc-4.5.2 I reduced
the problems to re/regexp failures.

Failed 6 tests out of 2044, 99.71% okay.
re/regexp.t
re/regexp_noamp.t
re/regexp_notrie.t
re/regexp_qr.t
re/regexp_qr_embed.t
re/regexp_trielist.t

This is the same test failure: each regexp_*.t test calls regexp.t

The tests pass with C<(cd t; ./perl harness re/*.t) but

./perl -Ilib t/re/regexp.t
# RT #89774
not ok 1539 # TODO () /s\xDF/ui:\xDFs:yT:$&:\xDFs => `T', match=
$subject = "\337s";

$got = "T";

;
$match = ($subject =~ m/s\xDF/ui) while $c--;
$got = "$&";

Before upgrading to ubuntu 11.04, I had no test failues, using gcc-4.6.0
After upgrading, gcc-4.6.0 would not compile perl: missing asm/errno.h

I tried upgrading to gcc-4.6.1 but it would not compile.
I put in a symlink from /usr/include/asm
and was able to build gcc-4.6.1 and to build perl,
but again I got the above test failure with perl.

I believe this has just been fixed with this commit:

If that is not the case, please holler and I will re-open the ticket.

I can't work out what version this actually is.

$ git show 9c8c35062b12e41237396ffd50b944586cbce3bf
fatal: bad object 9c8c35062b12e41237396ffd50b944586cbce3bf

The above description looks suspiciously like the problem solved by
Karl Williamson in:

commit 1b7228c
Author: Karl Williamson <public@khwilliamson.com>
Date: Thu Sep 22 17:34:35 2011 -0600

regexp.t: print diagnostics with leading '#'

Some test platforms don't like unexpected output without the comment
prefix character

But I'm confused as that was 3 days before the date of your bug report.
