Problem seems to be related to the ac.meta file. Removing this file fixes the problem.

It seems to be stuck in SG_CreateAmbCluster, one of the parser functions that handles ambiguities. Is it possible that you used the permissive parse table there? Those don’t work well with the C parser, as it cannot selectively enable/disable the recovery rules.
