GNUPlot file doesn't work for stats generated with -p <number> argument

[bondhugula]

With pmbw-0.6.2 or even the current git version (1a2f3ff96e6c9b8f9fc85084909edde6afac34ce), a plot generated with the stats.txt of a pmbw with a -p <number> yields:

./stats2gnuplot stats.txt | gnuplot
Parsed 23 RESULT lines in input.
         line 331: warning: Skipping data file with no valid points

gnuplot> plot '-' using 1:2 title 'p=32' with linespoints
                                                         ^
         line 331: x range is invalid

gnuplot 5.2 patchlevel 4 or even with patchlevel 8.
