fixing a parsing error

[kindtrojan]

The parsing assumes a 4 line header, which is removed and assumes to blank line. However, it appears to have blank lines in the output, which causes index out of range errors. Solution: 1) splitting on the last part of the header "objfile" to remove unwanted header lines, and then ignoring the blank lines while parsing.

The output to be parsed:

 process 502
