RE: mallinfo can't handle >2g values

[Matt Liberty]

If you run the test program I included with my original report it
doesn't show this working.  I seems to just top out below the current
usage.  Perhaps there are internal issues?

I would be happy if you fixed mallinfo to work with the casting solution
you give below or to have an alternate interface that uses longs.
Eventually linux will support 64bit applications and the casting
solution won't work, presumably this is why sun uses longs.

Thanks,

-Matt

Replying to myself, sorry:

It was just pointed out to me by Doug Lea that this is already the
case in the current code.  If you cast back the int values to
unsigned, the stats should be correct even if >2GB.
