Wrong match when minimum value is omitted in repeating qualifier

[etienne-s]

Using R:

grepl("ab{,2}c", "abbbc")
# [1] TRUE

I would expect either FALSE or an "invalid regex" error.

More details can be found in my original Stack Overflow question.

The documentation here indicates a missing lower bound is not expected. To return an error change lib/tre-parse.c line 631 to:
if (max >= 0 && (min < 0 || min > max || max > RE_DUP_MAX))
