Subject: Serious bug in EVAL ??
I've been testing a knowledge representation package, and found that when
I eval (with *fast-eval* t) a selection, a macro does not expand properly,
but when I eval (with *fast-eval* nil) it does work. It also works
when I step the function, or when I eval and run the individual forms. The
effect is that of an improperly expanded macro, but only in certain cases.
And it expands fine when I step through the code, making this one
hard to debug.
As far as I can tell, it appears to be a problem compiling a heavily
nested macroexpansion. If anyone's interested, I can probably give
you a copy of the code.
