MEMSTOMP(1)                            General Commands Manual                           MEMSTOMP(1)

NAME
       memstomp - detect function calls with overlapping memory regions

SYNOPSIS
       memstomp [-dk] application [argument...]

       memstomp -h

DESCRIPTION
       The  memstomp utility identifies function calls that use overlapping memory regions in situa‐
       tions when such an overlap is not allowed by various standards. When a problem  is  detected,
       memstomp  displays  a  backtrace  to  help  you  debug  the problem, and if executed with the
       --debug-info command line option, it even uses the available debugging information. Since the
       backtrace code is not thread safe, memstomp also allows you to use the --kill option to imme‐
       diately terminate the analyzed program when an invalid function call is detected.

       This version of memstomp inspects the following function  calls:  memcpy(),  memccpy(),  mem‐
       pcpy(), strcpy(), stpcpy(), strncpy(), stpncpy(), strcat(), strncat(), wmemcpy(), wmempcpy(),
       wcscpy(), wcsncpy(), wcscat(), and wcsncat().

OPTIONS
       -d, --debug-info
              Make use of debugging information to produce more detailed stack traces.

       -k, --kill
              Kill the analyzed application when a problem is detected.

       -h, --help
              Display usage information and exit.

       -q, --quiet
              Be less verbose
