When emerging perl-5.8.0-r??, the system slows down continuously while testing and lib/Config eats up more and more memory, resulting in the killing of user processes, and finally in the killing of the actual lib/Config test. lib/Config isn't the only test which exhibits this behaviour. If make tests is allowed to run further (isn't killed by the kernel which tries to handle OOM), the compilation freezes the computer on one of the Extutils/* tests. This error occurs while emerging perl during an emerge system (but also if emerged seperately) when running the emerge process inside a chroot environment on a working Gentoo system (Live-CD or working installation) when starting from a stage1 build. This error occurs once in a while, depending somehow on the underlying stage1 build, as rerunning the build from stage1 and then doing another stage2 emerge system solves the problem sometimes (without doing anything differently during the emerging of stage1). Hardware errors of this computer have been checked more than once in result to this error, and nothing seems to be obviously broken (at least as reported by memtest86). Total memory of this computer (including swap) is 1.5GB. Output of the actual emerge cannot be pasted, as the computer freezes in the process of the next test (Extutils/*). Reproducible: Sometimes Steps to Reproduce: 1. Start a stage1 build on a fresh stage1 tarball (x86) 2. Start scripts/bootstrap.sh 3. Start emerge system. Actual Results: The kernel starts killing user-processes to free memory for the lib/Config test, which is invariably killed itself when memory requirements can't be satisfied. Expected Results: lib/Config test succeeds and the perl build completes successfully.

I have never seen or heard of this before. If you want to disable the tests so that you can continue, it should be possible to comment that section out of the ebuild.
This bug seems so strange to me too, that I invariably thought that this bug must be due to a hardware failure, but I reran tests on all hardware again tonight, and there are none. I can reproduce this bug on pretty much every machine that I have access to. I've yet to try and see whether the bug goes away if changing the optimization settings of perl (-O3 shouldn't be the problem, but -march=athlon-xp or athlon maybe is, as several other programs start to segfault on exit too if built using a compiler which was optimized using -march=athlon-xp).

For the record, I've built perl literally hundreds of times on systems with either -march=athlon or -march=athlon-xp, and never seen anything like this.
Hi, i experienced simular problems while doing an emerge -u system on my gentoo box. While building libperl 5.8.2 it would spawn 1000s of make processes which would result in all memory being eaten up. After some investigation it turns out that my system date had somehow been set back to a few months previous and because of this the files in the perl tar archive were dated in the future (compared to my system date). Once i had set the system date to the correct value it fixed the problem and perl emerged succesfully. Regards, Aled
Is it possible that the system date was the problem? Still unable to reproduce this.
Please reopen this bug if it persists with perl 5.8.2 (inactive for a month now)
Problem has disappeared with Perl 5.8.2, I can confirm this.
*** Bug 54835 has been marked as a duplicate of this bug. ***
Well, hell, this is an old bug? Well, it's back. If you're gonna close my bug, please reopen this one! It's back! My question is: Why now? I don't know what changed to 'cause this.

I just tested to reemerge the already installed perl-5.8.2-r1. It didn't work neither. Also disabling all CFLAGS had no effect on the test-process.
I still get this problem as well. Can you at least add a use flag to not do the Perl tests?

Can you make sure /dev/null exists and is writable?
I can confirm, /dev/null does exist and is writable by all. It always memleaks on me in the tests.
I have also confirmed that /dev/null exists and is writable bash-2.05b$ ls -l /dev/null crwxrwxrwx 1 root root 1, 3 Dec 31 1969 /dev/null bash-2.05b$ echo test > /dev/null
Compiling with gcc 3.4.2 solved this problem. At least for me. Since gcc 3.4.2 is installed in an own slot it sounds safe to emerge it, change to it and then emerge / update perl. HTH
