It is freeing the state node marked as the start state for the second
atom(01), inside function xmlFAEliminateEpsilonTransitions, inturn invoked
from xmlRegexpCompile.
regexp: '(2){0,1}1'
3 atoms:
00 atom: charval once char 2
01 atom: subexpr once start -572662307 end 2 <<< start pointer is getting
freed
02 atom: charval once char 1
6 states:
state: START 0, 4 transitions:
trans: removed
trans: removed
trans: count based 0, epsilon to 4
trans: counted 0, char 2 atom 0, to 2
state: NULL
state: 2, 3 transitions:
trans: count based 0, epsilon to 4
trans: removed
trans: counted 0, char 2 atom 0, to 2
state: NULL
state: 4, 1 transitions:
trans: char 1 atom 2, to 5
state: FINAL 5, 0 transitions:
1 counters:
0: min -1 max 0
I am not sure whether this node is deleted because of some problem while
creation of
the automata or the problem entirely lies in function
xmlFAEliminateEpsilonTransitions.
Is the regular expression created correctly?? To me the third transition in
state 2, should move to state 4.
Any clues to take it forward??
Thanks !!
