Specifically MEMSTOMP will > detect calls to the following routines with overalapping memory arguments: > > [w]memcpy, str[n]cat, wcs[n]cat, str[n]cpy, wcs[n]cpy, [w]mempcpy, memccpy, > stp[n]cpy > > While valgrind can detect these cases, using a DSO such as MEMSTOMP can be > significantly faster. > > The MEMSTOMP code utilizes GPLV2+ and LGPL3 code. The GPLV2+ code is limited > to the backtrace code which is not thread safe and may need to be > disabled/rewritten. I assume this could be done as a system-wide LD_PRELOAD if desired?
