Thanks for the info, I updated

fwiw, the bug occurs when addresses do not fit in 32 bits.
for some reasons, I always run into it on OSX but not on Linux, ubless I
use dmalloc.
I replaced malloc with alloca (and remove free) so I always hit the bug
on Linux.
Thanks for the patch. It's a giant mess.
There are 1500 places in ROMIO where clang's "-Wshorten64-to-32" gives a
warning. Then there are cases such as this where we are explicitly
casting to an int -- clang won't warn about that, assuming we know what
we are doing (hah!)
