kdenetwork3 out of memory error

[mlh%goathill.org@localhost (MLH)]

Any clues as to why i386 gets this out of memory when compiling
kdenetwork3? This error has been occuring since January yet doesn't
with amd64.

kcminterface.cpp:3378:52: warning: null character(s) preserved in literal [enabled by default]
     printerListView->header()->setLabel( 2, tr2i18n( "Comment" ) );

cc1plus: out of memory allocating 3355443200 bytes after a total of 0 bytes
Makefile:609: recipe for target 'kcminterface.lo' failed

Why is it attempting to allocate all of physical memory?
