------- Comment #12 from pixel at mandriva dot com 2007-08-21 13:29 -------
i do know it works nicely with gcc 4.3
but i still get the "memory hog" behaviour using branches/gcc-4_2-branch, ie:
% /usr/lib/gcc/i586-mandriva-linux-gnu/4.2.1/cc1 -O2 fail.c
runs with memory RSS raising up to 1G many times.
i've also tried with gcc-4.2-4.2.1-4 from debian (which has a SVN snapshot from
20070812):
% ulimit -v 900000
% /usr/lib/gcc/i486-linux-gnu/4.2.1/cc1 fail.c -O2
