The memory needed by helgrind might depend on what your program does. Typically, it needs twice the original, but it might be a lot more.
Which version of Valgrind are you using ? In the SVN version, some memory improvements have been done. The best is to get the latest SVN version, compile it, then run with --stats=yes. That will give some indications where the memory is taken. More detailed information can also be obtained by using --profile-heap=yes Philippe ------------------------------------------------------------------------------ _______________________________________________ Valgrind-users mailing list Valgrind-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/valgrind-users
