It's not completely reliable, in case of functions that allocate far too much stack space. You might want to take a look at the gcc support that Andreas Krebbel implemented for s390 to check for stack overflows: http://gcc.gnu.org/ml/gcc-patches/2004-08/msg01308.html I think there are some additions planned for the next gcc release, but if you port this to i386, it will get you pretty far.
