Hi,

I first started out on OS X 10.9.4 with Xcode 3.2.6.

That was your first mistake :)

Xcode 3.2.6 was designed to run on OS X 10.6 and *only* OS X 10.6. Any strange behavior you see is par for the course when running in an unsupported, untested configuration..

Since I installed Xcode 5.1.1 alongside to it, I am experiencing weird
problems. Like this piece of test code

pxmempooltest1* mypxmempooltest1[dpxg1_test_mempool_count];

pxfor(i,dpxg1_test_mempool_count){
mypxmempooltest1[i]=new(pxmempooltest1)(i);
pxoka(mypxmempooltest1[i]->itsmempooltest1data==(123+i))
}

It simply allocates a fairly large number of instances of a simple class (on the heap). After some forty-thousand loops
no memory is allocated. This test code has worked ok for many years...

Is it ok to have these two versions of Xcode on the same machine?

No. It is not OK to have Xcode 3.2 on anything later than OS X 10.6 in the first place, regardless of whether or not you have Xcode 5.x installed. I would recommend, if you absolutely need to run Xcode 3, that you use a virtual machine running 10.6.
