Have you tried C-c C-c on each source block in the buffer? If one (or more)
fails, you know what to do.

If they all work fine, then I'd do a binary chop to get a minimal
example.  Then edebug org-babel-execute-buffer on the minimal example
(if the macro causes problems with edebug, define a new function,
org-babel-execute-buffer-do-not-save-outline-visibility, which does not
invoke the macro and debug that: if that works, then there is probably
some funky interaction with the macro.) In each iteration of the loop,
record the beginning of the match and the end of the match: that'll tell
you which block is being executed.

The simplest solution of course is to send the whole thing to Eric
