Help needed with Segmentation error

[raghav]

Friends, I require help with the segmentation error in GCC. I am trying to run my mos simulation program in GCC. No, actually I am running only one of arround 20 functions that I'll be using later.But each one has dynamic memory allocation [malloc()] several times. This I suppose is the reason for the segmentation error. I am in dire need for either a short term or a long term solution. Please help urgently.

Segmentation errors are almost always programmer errors. Most often, they indicate that you're trying to use a "bad" pointer. In another way, you got one or more major bugs in there.

There are several ways to debug them, one is by sprinkling your code with printf()s; another is to analyze the core dump, or use a debugger, There is also asserts, lint and purify, amongst other things.

For completeness sake, I should mention that hardware/library/compiler errors can also cause it, but don't even bother looking for those unless you're 200% certain that your code is correct.

Since you are using malloc, check if you are getting valid pointer? Next thing check the size passed to malloc, is it > 0?
