I'm trying to build IMP from SVN trunk source, but I'm having some problems with getting LPG to generate compatible ASTs. Which version of the LPG generator executable are you using for IMP development, and with what command-line options?

First off, thanks for the bug reports!

Ah, yes, sorry about that -- there was indeed a latent bug that resulted from
attempting to use an already-closed file handle, which could cause symptoms
like the one you encountered. It's been fixed in CVS HEAD, and today I released
LPG 2.0.23, which includes the fix.

Yes, it's entirely possible that the IMP Box plugin isn't quite up to date wrt
the LPG runtime. It just needs to have the parser re-generated from the grammar
file. I'll fix that ASAP.
