Hello ,
i am working on NetBSD 3.0.2 with gcc version 3.3.3 .
While debugging with gdb, i am getting a segmentation fault with
accept system call and gdb is showing following traceback.
Program received signal SIGSEGV, Segmentation fault.

Could anyone please suggest us what could have caused this

The same thing that always causes a segmentation fault: trying to use
memory that isn't yours or in a way that isn't allowed. Without
seeing the code it's impossible to give any more detail. Since you
mentioned BSD and are using system-specific functions your question
might be more appropriate for comp.unix.progr ammer where they
specialize in such systems.

I think that you use not a thread-safe library.
Please, provide more info.

Hi.
(a) Could you send the complete command line options including flags,
target, etc. what you are using to generate the exe.?
OR
Could you check (a) is being used properly with required library(s)
calls and flags during compilation.
I don't think you need to have any other big reasons of having SEGSEGV
error message..relax! !!!

I think that you use not a thread-safe library.
You don't need threads to get a segmentation fault (and there's
nothing here to indicate that the OP uses threads at all), it's
enough to have either memory corruption in your program or call
some library functions with wrong arguments (e.g. in another
thread somebody got a segmentation fault because he was passing
a NULL pointer to fclose()).
Please, provide more info.
That's definitely required to make any reasonable statements
beyond listing the "usual suspects".
Regards, Jens
