Hi all, I have some code which is doing some basic matrix calculations (for a perceptron classifier) and I've run into some problems with ocamlopt. It seems that the same code, which runs fine on my laptop (powerbook, mac os x > 10.2, ocaml 3.06) with ocamlopt and runs fine on a linux machine (athlon mp 2000+, 2.4.18-24.7, ocaml 3.06 using gcc 3.2), does not run on my work machine (pentium 4 2.26, debian 2.4.20, ocaml 3.06 using gcc 3.3.1). On my work machine if I just compile via ocamlc, the code runs fine. But if I do it to native code, I get (a) incorrect numbers after a certain number of iterations of my code, (b) a stack overflow after a few more iterations. I have no special ocamlopt flags set. I first thought maybe it's the binaries from debian that were at fault, but I tried recompiling but that did not help the situation.
What could possibly be at fault here? Is it ocamlopt? Is it debian? the kernel? Any help would be much appreciated. Below is some information on the work machine where ocamlopt is coughing up.
