Since this appears to be Windows (not explicitly said), the likely
change is the compilers used for R >= 2.14.2 differ from those used for
2.14.1. The posting guide does ask for 'at a minimum' information with
good reason. How big the change was depends on whether this was 32- or
64-bit Windows.
Unfortunately there are a lot of badly written packages out there which
write in memory they should not. As time goes on compilers get better
at optimizing, and that means they are better at keeping things in
places in memory close to hand that are more liable to get clobbered.
The only really effective way to find such things is to use valgrind,
and that means to use Linux (or perhaps Mac OS X, but that's flaky and
with a lot more overhead than on Linux). See R CMD check --use-valgrind.
And of course a new compiler may have a new set of bugs: but so far
we've uncovered about 50 errors in packages and none in the compiler.

Dear list,
My code runs on 2.14.1 smoothly (with no error) but makes R crash on
2.14.2
and 2.15.0 with the usual windows message about "R for windows GUI
front-end has stopped working..." and as such I dont have any access
to R
to get any error or warning message (if any). It crashes on random
parts of
the code any time that I run it.
The code consists of EDA and spatial regression and various loops
and optimizations. The goal of the code is to perform a complete
analysis
on various datasets.
Please take a look at the code here :

You are not likely to find people willing to debug 15553 lines of code
for you, and they are certainly not going to do it "by eye", without
the datasets!
One thing that jumps out is that you start off by loading five
external packages, either of which might be the true owner of the
problem. Even if the actual crash hits in the stats.dll, the
underlying issue could well be memory corruption occurring some time
earlier.
Things to try:
Run under Rterm in a command window instead of Rgui. That should at
least tell you how far you got before the crash, maybe even a proper
traceback.
Carefully try disabling parts of the code until the issue goes away.
The last item removed might hold the clue. If you can cut it down to
something small(-ish) and reproducible, people might be in a better
position to help you.
Is it really a random crash, or does the crash point move every time
you change the code slightly? If the former, you might have physical
computer problems or you might be running close to your memory limit.
Just a guess:
One more thing you could try is to rebuild your packages under 2.15.0.
One often forgets to update them after a version change of R:
update.packages(checkBuilt=TRUE, dependencies=TRUE, ask='graphics')

It seems that the results that comes out of 2.15.0 is more valid for my
work.
I cant think of anything that makes the code crash on the latest
versions.
Here is the error message from windows:
