[Chicken-users] valgrind - more details

[Jörg F . Wittenberger]

I managed to narrow the valgrind complaint's scope:

Try as a test:

valgrind --log-file=/tmp/csi.vg --track-origins=yes csi -e "(vector 'a 'b)"

The result in /tmp/csi.vg looks good.

However try:

valgrind --log-file=/tmp/csi.vg --track-origins=yes csi -e "42"

and run into an example of the problem like this:
