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 raisin

more info: the tree-vrp issue is raised by ivopts pass:
without ivopts:
D.1541_13 = 3 - i_31;
D.1542_14 = (unsigned int) D.1541_13;
D.1543_15 = D.1542_14 * 4;
D.1544_16 = (int *) D.1543_15;
with ivopts:

miscompiles with gcc 4.2 -O2
here is a simple test case reproducing the issue.
eg:
% gcc -O2 ivopts-

i forgot to say it doesn't occur without -O, and occurs with -O, -O2
/usr/lib/gcc/i586-mandriva-linux-gnu/4.2.1/cc1 -O fail.c
