(Not sure what you've found with your search.) Borland has a plug-in memory management architecture, whereby you can (well some people can) replace the memory manager functionality. A replacement memory manager (borlndmm.dll), is part of product installation, installed in the ...\bin directory of the installation tree. Borland's memory manager (since at least bds2006) is apparently a copy or derivative of the FastMM memory manager (http://sourceforge.net/projects/fastmm/). Borland's libraries are implemented such that a plugin replacement memory manager will _not_ be used if an application/dll is linked with static libraries (at least with bds2006.) You might want to redirect this topic to the .rtl newsgroup, wrt/ B/CG's runtime library implementation.
