floating point exception while operating on empty container

[yarikoptic]

e.g. when something like this (reading 2nd read of the same opened file):

 $> python -c 'import blosc; f=file("/home/yoh/.emacs", "rb"); print 1; blosc.compress(f.read(), typesize=8); print 2; blosc.compress(f.read(), typesize=8); print 3;'

zsh: floating point exception  python -c

Yes. This happens because your are telling blosc to compress a buffer with less bytes than the base type. Here it is a clearer example:

>>> import blosc
>>> blosc.compress("1"*8, 8)
'\x02\x01\x03\x08\x08\x00\x00\x00\x08\x00\x00\x00\x18\x00\x00\x0011111111'
>>> blosc.compress("1"*7, 8)
Excepció de coma flotant

That should be fixed indeed.

Synced with blosc 1.1.2 (closed by fa5d163).
