Problem with pthreads (serious memory leaks)

[Arash Partow]

Hi all,

I'm encountering some memory leaks when using pthreads under cygwin.
As usual the code has been compiled/run on other *nixes (openbsd3.7,
netbsd2.0 and mandrake10.1) and the leak does not seem to occur.

The system specs are as follows:

1.) gcc 3.3.3
2.) cygwin dll, snapshots as of:
    3/6, 1/6, 28/5, 24/5
    (all produce the same result - haven't test earlier version to
    see where the break comes from.)
3.) WinXP Pro SP2 and WinXP Pro 64 SP1
4.) Dual AMD 64 4k
5.) 4 gig RAM


Example code can be found here:

To make and run do the following

make all

./example1


using taskmanager or sysinternals or taskinfo one can see that
there is a huge amount of memory being leaked within cygwin1.dll

the other examples demonstrate the same effect but much quicker.



any ideas on whats going on?
