Can you test the 1.4.1 binary on the 1.5 system to confirm it
is a library/toolchain rather than a kernel issue (copying
a.out libraries across into /usr/lib/aout and using the
uuencode a.out ld.so from 1.5).
Assuming it is userland/toolchain, could it be the new malloc
library - does "ln -sf R /etc/malloc.conf" have any effect?
