It looks as a tcmalloc bug which could be fixed; it also has been probably fixed in the meantime as stated there. > I think a key point here is to reduce the number of allocators being > used by the distribution so we can keep the quality high and help > our users when they have problems. So why glibc greated an N+1 allocator (by DJ Delorie) instead of just importing/using tcmalloc (which is license-compatible with glibc)?
