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 situations 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 immediately terminate the analyzed program when an invalid function call is detected.

This version of memstomp inspects the following function calls: memcpy(), memccpy(), mempcpy(), 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
