Cache the header:
f = File('/Downloads/libLAS-1.6.0b3/test/data/1.1_1.las')
h = f.header
for i in xrange(15000):
temp = h.offset
As far as the reason why it runs out of memory? Bad design :) Putting the
f.header call inside the inner loop means constructing a python header object
every time. This was leaking header objects, and has been fixed in the main
branch.
Thanks for the report,
