           Summary: mergecap fails when "time_t" is "int"
           Product: Wireshark
           Version: SVN
          Platform: PC
        OS/Version: OpenBSD
            Status: NEW
          Severity: Minor
          Priority: Low
         Component: Extras
        AssignedTo: wireshark-bugs@xxxxxxxxxxxxx
        ReportedBy: nikns@xxxxxxxxx


Build Information:

--
When "time_t" is "int" (for example on OpenBSD), mergecap fails because of:

-----------merge.c-------------------------
[..]
wtap* merge_read_packet(..) 
{
struct wtap_nstime tv = {LONG_MAX, LONG_MAX};
}
[..]
-----------wiretap/wtap.h------------------
[..]
struct wtap_nstime {
        time_t  secs;
        int     nsecs;
};
[..]
--------------------------------------------

As you see, if "time_t" is "int", "LONG_MAX" assignation overflows "tv" value.

The solution would be to make "wtap_nstime" element "secs" of type "int" and to
"tv" assign INT_MAX.
