After some googling I have found that ABI means application binary interface
and how this affects the problem, thank you.

I would be happy if someone could direct me to a tutorial on how to maintain
two different ABIs on the same machine (so as not to break unaligned code
elsewhere) and how to obtain it precompiled from a package maintainer.

As another workaround, it has been indicated that $LD_PRELOAD may be used to
link to an aligned malloc

For information on how to do either I, and I'm sure many others attempting to
call SSE functions or DMA transfers from 32 bit gfortran, would be very
thankful.
