strcmp core dumps

hi everyone, Right now when I do: strcmp(s1, s2); i get a core dump because at times s1 or s2 can be nothing so that makes strcmp() core dump. What is the solution, if at times I expect one of them (or both) to be NULL? I want to be able to compare that s1 is NULL and s2 is "blah" or...

Using GDB to analyse different CORE dumps

Hi, Can we modify the GDB source code so as to analyze core dumps from different targets? From my analysis, I think we need to build our section table statically for each target. i.e., including the various address boundaries in build_section_table() function. If this is the case, then the GDB...

AIX core dumps

My program is not dumping core when hitting a segmentation violation inside a thread. However, it dumps core when the segv occurs within main. Any ideas on how to diagnose this? AIX 5.3

core dumps

i had a situation where a process was defunct. preap would not reap the process and gcore would not work properly (not sure why). therefore, the suggestion was to force a panic and collect the core dump. obviously you could do a savecore -L and capture the dump without bringing down the system....

Stack only core dumps

I'm working on a program in Linux with a group of people scattered around the country. When we have a crash, I like to send a core dump to the appropriate person so that they can understand the problem better. The problem is that our application uses several gigabytes worth of data and these...

Generate core dumps

kill -SEGV <pid> gives me the core file for that process but also terminates the process. Can I not get the core dump without terminating the process ?

crash

CRASH(8)						    BSD System Manager's Manual 						  CRASH(8)

NAME

     crash -- examine and debug system images

SYNOPSIS

     crash [-M core] [-N kernel]

DESCRIPTION

     The crash command is used to examine and debug system images.

     If run without any arguments, crash operates on the running system.

     The options are as follows:

     -M core	   Operate on the specified crash dump instead of the default /dev/mem.  Crash dumps should be from the same version of the system
		   and same machine architecture as the running version of crash, and must be uncompressed.

     -N kernel	   Extract the name list from the specified kernel instead of the default /dev/ksyms.

     The command syntax used by crash is the same as the in-kernel debugger.  See the ddb(4) manual page for more information.

     Operations and facilities that require a running system, such as breakpoints, are not supported by crash.

     crash does not provide pagination.  However, by using the pipe symbol, output may be sent to commands available from the shell.  For example:

	 crash> ps | more
	 crash> ps | grep ioflush

SEE ALSO

     ps(1), vmstat(1), ddb(4), pstat(8)

HISTORY

     The crash command appeared in NetBSD 6.0.
