how to show cause of segmentation fault with gdb

Hi,

the last days I faced the following problem. I was writing a
program that used 
c-client library. I defined and assigned a

char *myvar;

and the function expected a 

char myvar[];

Because a deeper function needed write access to that
variable the program 
stopped with a segmentation fault. Someone else gave me a
hint which is most 
likely the cause of the error. But he guessed, actually.

Is there a safe way show the cause of that error using gdb.

Best Regards,

Oliver

No, not really.
