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: http://perl5.git.perl.org/perl.git/commitdiff/1b7228c9af6

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 1b7228c9af61f2feb164874a11b82557fc988b5f 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.
