| 01:44 | Lemon change: compile the resulting parser with -DYYSTACKDEPTH=0 or set the "%stack_size" parameter to 0 in the grammar and the parser stack will be dynamically allocated using realloc() and free(). The default behavior is to have a finite depth stack. (CVS 3738) check-in: 06719b74 user: drh tags: trunk | |
