Problem with delete[] in class destructor

[Nicolas Wack <nwack at iua dot upf dot es>]

Hi all!

I have a little problem, and I thought maybe someone could help me out 
before I go crazy!!
Here's a simple file that allocates some amount of memory (roughly 
300MB), sleeps for 5 secs, deallocates it and sleeps for 15 seconds.

I know for sure that the program goes through all the destructors, 
however nothing gets freed...
I can also reproduce this behavior (bug?) by replacing the Test class 
with std::vector, for instance.
Also, calling v[i]->destroy() instead of deleting the object doesn't do 
anything neither...

Can somebody tell me what's wrong? Is that a problem with gcc or the 
libc or libstdc++?

Thanks in advance!

Nicolas.
