possible memory leak in vintrp?

I am putting a lot of high frequency CAM hybrid data on pressure
levels using Ngl.vinth2p.
I have used this routine many times before.
But this time , the number of calls per day exceeds 1500.
One day goes OK, the data look reasonable but on the second day I get
the error that is at the end of this message.
It appears that Ngl has a memory leak that is exposed when the routine
is called this many times.

I am on OS X 10.5.8, using pyngl 1.3.0b1, python 2.6.1, numpy 1.3.

python(98559) malloc: *** mmap(size=36864) failed (error code=12)
*** error: can't allocate region
*** set a breakpoint in malloc_error_break to debug
Bus error
