Debug crash using C Map file in linux?

I have seen a document here http://www.codeproject.com/Articles/3472/Finding-crash-information-using-the-MAP-file. This example is all about crash seen in Windows file? I am looking for the same mathematics that has been done here for the crash generated on Linux systems. If I get the crash on Linux, then how will I debug the issue in the similar lines like Microsoft document http://www.codeproject.com/Articles/3472/Finding-crash-information-using-the-MAP-file. Please help? Is load address and the code segment address are same in Linux? what is the following in Linux as mentioned in the link "The first part of the binary is the Portable Executable (PE), which is 0x1000 bytes long."?

PE is windows format. Linux uses ELF. Of course you can parse ELF manually, but you shouldn't - gdb could do that for you. Even more, you can use addr2line utility to map address to file/line in source code (of course both of these will require debug build).

Map files are rarely used in linux - it usually just a part of debug executable. It could be dumped from debug build, however, but it don't have too much practical value.

Also, take a look at How to use addr2line command in linux
