 Here is a recursive lens used for a regular language.

 {{{
 let input = "1zz1aa22zzz22aaa333zzzz333aaaa"
 let rec idr = [ key /[0-9]+/ . del /[z]+/ "z" . store /[0-9]+/ . del
 /[a]+/ "a" ] . idr?
 test idr get input = ?
 }}}

 A segfault occur while parsing the input string.

 {{{
 Program received signal SIGSEGV, Segmentation fault.
 0x00157b8b in visit_exit (lens=0x806b6f8, start=30, end=30,
 data=0xbfffed74) at get.c:951
 951             uint n = (top_frame(rec_state)->lens == lens->child) ? 1 :
 0;
 }}}
