All of these line numbers are exactly 2x the actual line number in the source. I assume there's a bitshift bug somewhere. The first one is actually line 323, e.g.

hmm, are you sure you recompiled/reinstalled memprof with the ruby version you were using. this usually happens if you re-use a memprof build across ruby builds (ree vs ruby1.8 especially)

also you can try running ruby spec/memprof_spec.rb, which tests line numbers

I installed memprof for ruby 1.8 and then for REE (you can see the version in the output above). Perhaps it used the MRI version somehow but I don't know for sure.
