[hardy] [mawk] match() works in exponential time even tough the ~ doesn't

[PapaTom]

Binary package hint: mawk

BEGIN {
 comment = "\\/\\*([^*]+|\\*+[^*\\/])+\\*\\/"
 #The more the 'A' characters, the longer match() takes to complete (exponentially).
 line = "/*AAAAAAAAAAAAAAAAAAAAAAAAAAA*/"

 if (line ~ comment) {
  print line " matches " comment
  match(line, comment)
  print "the match is at [" RSTART ".." RSTART + RLENGTH "]"
 }
 else
  print "Does not match"
}
