Hi,
The attached file will cause an out of bounds heap write (heap
overflow) in the function make_regexp.
This is a different bug from the two others I already reported, it
still happens with the latest git code.
The file just consists of the chars "/\" and a zero byte.
This was found with the fuzzing tool american fuzzy lop.
