I did git bisect on a couple of x86_64 Linux systems:
- RHEL 6.7 with Emacs 24.3.2
- Fedora 22 with Emacs 24.5.1

The result was

# first bad commit: [6d2ab4071960f8a7f20138291424b468722ab522] org-table: Fix 
radio tables containing macros

The table I ran M=x org-plot/gnuplot on was from the Org Mode info page
"Org-Plot":

     #+PLOT: title:"Citas" ind:1 deps:(3) type:2d with:histograms set:"yrange 
[0:]"
     | Sede      | Max cites | H-index |
     |-----------+-----------+---------|
     | Chile     |    257.72 |   21.39 |
     | Leeds     |    165.77 |   19.68 |
     | Sao Paolo |     71.00 |   11.50 |
     | Stockholm |    134.19 |   14.33 |
     | Morelia   |    257.56 |   17.67 |

Stack backtrace is as mentioned earlier:
