It does not directly contain the code for new/delete/malloc/free/whatever, but I'm pretty sure that _if_ you're linking with the dynamic runtime libraries (_not_ the static libraries), new/delete/malloc/etc will eventually call into it. in bds2006, in the installation tree (with library source), the implementations of the various items are located in <bdsinstalldir>\source\cpprtl\Source\memory\.
