(or something)
The following program segfaults when run under JIT.
.sub _main
newsub P0, .Sub, _echo
$S0 = "abcdefghij"
savetop
restoretop
end
.end
.sub _echo
print P5
invoke P1
.end
(note that I never call _echo, but the newsub is required to produce
the bug)
Strangely, it doesn't segfault when $S0 is set to "abcdefghi", or
anything of that length. In that case, it will likely differ from
system to system.
I'm running i686 Linux under gcc version 3.2.2. I have a modified
i386/jit_emit.h so it will (supposedly) work under this gcc which
looks like:
Index: jit_emit.h

This fix has worked fine with JIT until now, so I suspect the problem
is elsewhere.
