6.1 Known Bugs
==============

Large repetition counts in the ‘{n,m}’ construct may cause ‘grep’ to use
lots of memory.  In addition, certain other obscure regular expressions
require exponential time and space, and may cause ‘grep’ to run out of
memory.

   Back-references are very slow, and may require exponential time.
