I can confirm that I get the same peculiar behaviour on
newLISP v.10.6.0 32-bit on Linux IPv4/6 UTF-8 libffi.
using xubuntu 12.04.5

With the debug clause, even at its very first stop, before any user interaction, the format argument has got filled in with (null) and a number replacing %s and %d.

.. and the same with today's 10.6.2 (built using configure-alt)

Upon inspection, I would suggest that that varPrintf call at nl-debug.c:355 (referring into today's 10.6.2 tgz) is changed to include an "%s" format string before the strStream.buffer. As is, the buffer contents is treated as a format string.

Likewise for many (most?) varPrintf calls.

In human speak: it appears there is a bug such that one cannot safely debug code that includes format specifiers like %s and %d. To debug such code, you need to lift out all such specifiers, or the format strings in full, into constants or similar. Likewise, function results must also not include any format specifiers.
