You do realize those calls are deprecated - umtpx is probably what is being used on your system.

I ran your code on my Solaris box - no problem. It still supports umtp calls. Go into your debugger and view all of your variables as you step thru the code.

Plus you should be using sizeof instead of a numeric constant for each element to strncpy, and bzero is not in your headers, try gcc -Wall for warnings.

memstomp

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 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

SEE ALSO

       memcpy(3), memccpy(3), mempcpy(3), strcpy(3), stpcpy(3), strncpy(3), stpncpy(3), strcat(3), strncat(3), wmemcpy(3), wmempcpy(3), wcscpy(3),
       wcsncpy(3), wcscat(3), wcsncat(3)
