I suspect that whatever the allegro issue is only happens on x86 and I

so if it is something in some assembly code in allegro then it is
probably different on 64 bit.
I'll try and build a 32 bit version over the weekend and see if I can
work out what the problem is.
I've played with a 32 bit version now and it is indeed related to some
custom assembly code in allegro - it's a seriously vintage x86
instruction that does something funky with a segment prefix.
It looks like valgrind is claiming to translate the instruction (which
is quite surprising as it rejects a lot of stuff involving segment
registers) but is doing so wrongly leading to the kernel forcing a segv
probably due to an underlying hardware trap of some sort.
