Hello,

I'm having strange problems with binary file output.  In my application I'm
preparing the [Word8], then doing just 4 operations:

1. openBinaryFile
2. newListArray from my list
3. hPutArray
4. file close

Everything works ok till I change one function deep in computational code.
The change is like this one:
was:
foo :: ...... -> Double
foo params = result where .....

now:

foo :: ...... -> Double
foo params = result*g(params) where .....

After the change, while the list is of the same size (I've traced the list
size and array size), the output is of different size! While the array has
849,352 the resulting file is 10K larger. I've tried to write the elements
from array using hPutChar instead of hPutArray. The file still has the size,
not equal to array size. 

Unfortunately, any attempts to product small self-contained example have
failed. But I can easily reproduce it in my app. Any ideas what should I try
to nail down the problem? May this be a buffering issue? Can I turn buffers
off/make them larger?

Regards,
Mike
