My little test dprofpp scambler produces a 133 line tmon.out. Here is the section of tmon.out that causes dprofpp a problem:

@ 10 0 0
& 14 DBI::st execute
+ 14
@ 0 0 2
- 14
+ 11
- 11
& 15 DBI::st fetchrow_hashref
+ 15
& 16 DBD::_::st fetchrow_hashref
* 16
& 17 DBI::st fetch
* 17
- 17
& 18 DBI::st FETCH
* 18        << here is the line dprofdd complains about
- 18
+ 11
- 11

Interestingly, the three lines for sub 18 appear to be the same as the three lines for sub 17. Unfortunately, I dont really understand the tmon.out '*' mark enought to know if the first occurance is ok and the second is faulty. If I change the '*' mark to a '+' mark, dprofpp has no problems.

I am leaning towards a dprofpp bug?
