Dmalloc is a debug malloc library for C and C++ users

The debug memory allocation or dmalloc library has been designed as a drop in replacement for the system's malloc, realloc, calloc, free and other memory management routines while providing powerful debugging facilities configurable at runtime. These facilities include such things as memory-leak tracking, fence-post write detection, file/line number reporting, and general logging of statistics.

The library is reasonably portable having been run successfully on at least the following operating systems: AIX, BSD/OS, DG/UX, Free/Net/OpenBSD, GNU/Hurd, HPUX, Irix, Linux, MS-DOG, NeXT, OSF, SCO, Solaris, SunOS, Ultrix, Unixware, Windoze, and even Unicos on a Cray T3E. It also provides support for the debugging of threaded programs.

Are there standard workarounds for dmalloc's assumptions on vsnprintf?
