Basically, you use a debugger. Since you did not specify an OS I'll assume you have
gdb. You must have compiled the file
in order for symbols to be available. If you are analyzing a core dump of somebody else's code you are in trouble.
The core dump file is called core
This will show you a backtrace (stack dump) of the call tree that lead to the crash.
You will have to find using the stack dump where in the code (not in a C library) the crash occurred. In other words the last line of the program's code that actually led to the crash.
Hi folks,
I'm hoping someone would be charitable enough to give me a quick explanation of adb usage for analyzing core files...or point me in the right direction. A search here revealed scant results and web searches are providing me with ambiguous information.

Hi,
I just wanted to know is there any tool avaliable for core analysis on hp-ux. I have heard about q4 utility. But I think it is used for analysis of system crash dump and not for core dump produced by a user process.
gdb doesn't give much information unless the binary is debug-build.

Hello,
I'm new to the group and this is my first post. I'm hoping someone can help me out. I have a core dump that I need to analyze from a Unix box and I've never done this sort of thing before. I was told to run a pmap and pstack on the core file which provided two different output files. ... (3 Replies)
How can we analyze a core file and determine why it was generated on a solaris system?
I know file core filename will tell us what program generated the file. But, what to do next to get more details?
Thanks, (5 Replies)
We have just enabled core dump on our RHEL5.7 OS. the java process is terminating very often so we enable core dump to analysis the issue and find below in core dump file.
Core was generated by `/usr/java/jdk1.6.0_06//bin/java -server -Xms1536m -Xmx1536m -Xmn576m -XX:+Aggre'.

Bio::Tools::Analysis::SimpleAnalysisBase(3pm) User Contributed Perl Documentation Bio::Tools::Analysis::SimpleAnalysisBase(3pm)NAME
Bio::Tools::Analysis::SimpleAnalysisBase - abstract superclass for SimpleAnalysis implementations
SYNOPSIS
# not to be run directly
DESCRIPTION
This class is a generic implementation of SimpleAnalysisI and should be used as a base class for specific implementations.
Modules implementing SimpleAnalysisBase only need to provide specific _init(), _run() and result() methods, plus any get/set methods for
parameters to the analysis program.

APPENDIX
The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
new
Usage : $job->new(...)
Returns : a new analysis object,
Args : none (but an implementation may choose
to add arguments representing parameters for the analysis
program. Each key value of must have a method implemented
for it in a subclass. A seq () method is provided here as
this will probably be needed by all sequence analysis programs
seq
Usage : $job->seq()
Returns : a Bio::PrimarySeqI implementing sequence object, or void
Args : None, or a Bio::PrimarySeqI implementing object
analysis_name
Usage : $analysis->analysis_name();
Returns : The analysis name
Arguments : none
analysis_spec
Usage : $analysis->analysis_spec();
Returns : a hash reference to a hash of analysis parameters. See
Bio::SimpleAnalysisI for a list of recommended key values.
Arguments: none
clear
Usage : $analysis->clear();
Returns : true value on success
Arguments : none
Purpose : to remove raw results from a previous analysis so that
an analysis can be repeated with different parameters.
input_spec
Usage : $analysis->input_spec();
Returns : a reference to an array of hashes of analysis parameters. See
Bio::SimpleAnalysisI for a list of recommended key values.
Arguments : none
result_spec
Usage : $analysis->result_spec();
Returns : a reference to a hashes of resultformats. See
Bio::SimpleAnalysisI for a list of recommended key values.
The key values can be used as parameters to the result()
method, the values provide descriptions.
Arguments : none
