#51158 [Opn->WFx]: abnormal memory consumption during build of 5.3.1 (and 5.3.0)

ID: 51158 Updated by: rasmus@php.net Reported By: stolen dot data dot net at gmail dot com -Status: Open +Status: Wont fix Bug Type: Compile Failure Operating System: openbsd PHP Version: 5.3.1 New Comment: Sorry, optimizing memory during the build isn't something we can worry about. Even my tiny $300 Netbook here has 2G of ram. If you can't find a machine to build on with enough ram, you will have to build with -O0 which should make it build for you. Of course, it won't be as fast.

Reproduce code: --------------- ./configure --prefix=/usr/opt/php --with-apxs=/usr/opt/apache/bin/apxs --enable-sqlite-utf8 --with-zlib --with-mcrypt --enable-mbstring --disable-xmlreader --disable-xmlwriter --without-pear --disable-libxml --disable-dom --disable-simplexml --disable-xml --disable-phar make Expected result: ---------------- well... Actual result: -------------- beyond 750mb of ram required; machine crashes when swap memory is exhausted ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=51158&edit=1
