[sqlite] Lemon behavior
I'm using Lemon for a non-sqlite related project and it is exiting with an assertion failure that I would like to understand. I have extracted the following small set of productions from a larger grammar. The "list" production happens to be the start symbol in the larger grammar. list::= list DELIMITER command. list::= command. command ::= TERMINAL1. command ::= TERMINAL2. When I place these in a .y file by themselves and build the file, Lemon fails with: Assertion failed: apx->type==SH_RESOLVED || apx->type==RD_RESOLVED || apx->type==SSCONFLICT || apx->type==SRCONFLICT || apx->type==RRCONFLICT || apy->type==SH_RESOLVED || apy->type==RD_RESOLVED || apy->type==SSCONFLICT || apy->type==SRCONFLICT || apy->type==RRCONFLICT, file lemon.c, line 1065 The odd thing is I use this pattern to parse lists of things elsewhere in the grammar without issue.
