CygWin .pyd oddities

Hi there.  I've been working on converting some of the more
math-intensive operations to C from a python script; and after some
trial and error (err, a LOT of trial and error) I have been able to
make a callable extension using CygWin.

I can use it fairly easily under Windows (there was a bit of a problem with the
feof() macro apparantly not working, so I added a || to the statement
to check for a char==-1) but now for some reason it has been taking
issue with my memory management.

I'm using a GPL'ed block allocater called blalloc which worked
*perfectly* under cygwin.  Upon transferring to W95, however, as near
as I can trace it the extension crashes in a free() statement that I
don't think it should.  (It doesn't crash immediately; not until near
the end of the program does it go down in flames.)

All of this is pretty irrelevant (unless there's a malloc() difference
I ought to know about!) - I would like to know if there's a method of
debugging a C extension in python.

Thanks!
