[bug-gawk] gawk bug

[Steven Daniels]

I'm getting an Assertion failed when I try the following:

$ echo '很?pos=ad 宽广?pos=va ， 更?pos=ad 是?pos=vc1' | gawk '{match($0, /(([^ \?.]*\?pos=ad |([^ \?.]*\?pos=(jj|va) )[地]\?pos=dev ){0,2})/ , arr)}  { if(arr[0]) print arr[1], arr[4], $6} '

Assertion failed: (&musts[2] <= mp), function dfamust, file dfa.c, line 3951.

[1]    13263 done       echo '很?pos=ad 宽广?pos=va ， 更?pos=ad 是?pos=vc1' |

       13264 abort      gawk

The point of failure seems to be "[地]", when brackets aren't used, the command works as expected.

$ echo '很?pos=ad 宽广?pos=va ， 更?pos=ad 是?pos=vc1' | gawk '{match($0, /(([^ \?.]*\?pos=ad |([^ \?.]*\?pos=(jj|va) )地\?pos=dev ){0,2})/ , arr)}  { if(arr[0]) print arr[1], arr[4], $6} '  

# => 很?pos=ad

$gawk --version  

GNU Awk 4.0.2

Thanks.
