Failure build log (fail.txt,7.68 KB, text/plain)

Description Craig Edwards 2007-06-03 11:45:45 UTC
When building opal 2.2.6 from the ebuild, my system terminates the build process every time at transcoders.cxx. I have 256mb of ram in my system, and 1gb of swap, and i have attempted this process with nothing running but sshd. Therefore, it leads me to believe that poor practices in this library cause it to claim far too much memory during the build process. The last error indicates over a 140mb malloc() which is far from sensible.

Reproducible: Always

Steps to Reproduce:

Actual Results:  
Build crashes, out of memory.

Expected Results:  
Software should install correctly without requiring over 500 megs of swap and 200 megs of ram free.

Failure build log

This is from the system with nothing running but sshd and dhcpcd. X and all X apps were not running.
Comment 2 Craig Edwards 2007-06-03 11:48:56 UTC
Correction, there is 512mb swap not 1gb, however this would indicate a 768mb build process for one c++ file, which is still beyond the realms of sensible.
Comment 3 Jakub Moc (RETIRED) gentoo-dev 2007-06-03 11:51:54 UTC
And, why is this a Gentoo-specific bug? Have you verified it's different somewhere else?
Comment 4 Craig Edwards 2007-06-03 11:53:05 UTC
I was told to place this bug here by the freenode #gentoo channel, when asked "who's tracker does this belong on".
Comment 5 Craig Edwards 2007-06-03 11:55:32 UTC
Just to point out this does seem to be well known on google too -

Don't know why i was told to put it here.
Comment 6 Jakub Moc (RETIRED) gentoo-dev 2007-06-03 12:06:36 UTC
Indeed nothing Gentoo could solve here; you can work around this by making more swap available (temporary swapfile or whatever); anything else needs to be done upstream (opal or GCC or both :))
Comment 7 Craig Edwards 2007-06-03 13:09:49 UTC
It looks like there is something gentoo can do :-)

This only occurs is -Os is used with the build flags. A possible suggestion would be to mask -Os in this ebuild (i have seen other ebuilds mask CFLAGS off). Is this a sensible request?

genstef - if you feel like doing some replace-flags magic...

jup have added it for now, thanks

What's your emerge --info, normally?

Recently upgraded from an obsoleted profile.
It's not really a 386, as the CHOST might lead you to believe, but when i installed this laptop two years or so ago, i picked the wrong architecture, and now i cant change that without a reinstall. Just to let you know...
Comment 12 Jakub Moc (RETIRED) gentoo-dev 2007-06-04 17:42:45 UTC
(In reply to comment #11)

gcc-3.3.x is EOL-ed.

Anyway, completely unrelated to this issue.
Comment 13 SpanKY gentoo-dev 2007-07-07 17:40:25 UTC
screwing with flags is not correct ... especially considering the problem you're "solving" fluctuates between gcc versions and packages
