git grep -P fatal: pcre_exec failed with error code -8

[Дилян Палаузов]

Hello,

with git 2.14.3 linked with libpcre.so.1.2.9 when I do:
  git clone https://github.com/django/django
  cd django
  git grep -P "if.*([^\s])+\s+and\s+\1" 
django/contrib/admin/static/admin/js/vendor/select2/select2.full.min.js
the output is:
  fatal: pcre_exec failed with error code -8

(But not with
git clone https://github.com/select2/select2
cd select2
git grep -P "if.*([^\s])+\s+and\s+\1" dist/js/select2.full.min.js

as the two select2.full.min.js files differ slightly in their size)

Any ideas?

Regards
