Whatever source you are using cannot be the original Lea malloc, since it does not do garbage collection. There are many comments indicating that the GNU C library uses a derived version of Lea malloc. You must be using one of the derived works that implements a conservative non-copying garbage collector. The Boehm-Demers-Weiser collector is a similar system but I do not believe it is based on the Lea malloc code. > The latter seems to indicate, that current copying GC has problems with > massive live data, where significant amounts of memory must be copied > around, i.e. bigger real life apps ;-) This is a well understood problem with copying collectors, and is the reason that the current state of the art is generational garbage collection, which scans/copies longer lived data less frequently as it is more likely to remain live. -- Jason
