Doc Text: |
Cause:
For some regular expressions DFA analysis can insert up to double "positions" than there are leaves.
Consequence:
There are not enough room to insert all the positions which may lead to crash for some REs.
Fix:
Space allocation for twice as many positions as there are leaves.
Result:
Enough space, no crash.
