     23// Most of the other statistics features are deactivated only by defining
     24// NO_STATISTICS (or their NO_%_STATISTICS macro). However the heap has some
     25// other compatability concerns and will disable itself in some cases.
     26//
     27// I do not claim to understand these cases. But TCMALLOC is often defined by
     28// default and you can pass --disable-gprofiler to configure to remove it.
