ah sorry, you mentioned it in another email, but I saw it too late.

Fairly so, but that string is explicitly written at every use of bug(), so 
it's not typo-proof (think about copy-paste...). For example, if it says 
"consistency check failed: canvas_undo", you don't know because 
canvas_redo misreports itself as canvas_undo. This is why I love macros.

However, in this case, there's only one bug("atom_string"), so you know 
which one it is.

Check whether you might be printing any uninitialised atoms... including 
memory that has been cleared with zeroes, as this is invalid in Pd. Also, 
setting an .a_w.w_ field does not in itself set the .a_type field, and I 
suppose that it's a common possible mistake to forget this.
