This is some sort of memory-management issue. Wading through the
program via gdb shows up that dead/gc'd objects are used somewhere.
The blanks/displays/comments just change the memory layout and
the GC frequency, since the code is interpreted and such performs
more allocation and GC.

I get errors with both versions of the runme-script, for example.
Since you are running csi with the -q option, any existing .csirc
is loaded. In my case, it loads the debug egg. Without the debug
egg the code works fine. Do you have a .csirc on your system?

I assume the swig-wrapper leaks some data-references somewhere,
but I'll have to gdb some more...
