Hi all,

Since Stefano reported memory leaks caused by regular expressions - TPRegexp in PndEmcStructure, I have replaced it by sscanf (rev. 9846).

However I didn't manage to check how it affected memory leaks by myselfe.

Running

valgrind --tool=cachegrind root -b run_sim_tpccombi_dpm.C

I do not have such an informative output as reported by Stefano but just

==5031== L2 miss rate:        0.2% (    0.1%     +     0.2%  )



I suspected that it was due to external packages compiled without debug info, but I recomplied it with debug info and it didn't help. Maybe I don't run valgrind with proper flag?
