Segmentation fault: where is the bug?

[giuliano]

Hi all: these lines of program cause a segfault on my Linux machine:

/* testptr.c */
/* gcc -o testptr -Wall -g testptr.c */
int main() {
char *name = "Giuliano";
*name = 'X'; //here I get a seg. fault
return 0;
}

I've tried to found the bug using GDB:
gdb testptr
Starting program: testptr
Breakpoint 1, main () at testptr.c:2
2 char *name = "Giuliano";
(gdb) step
3 *name = 'X';
(gdb) step
4 return 0;
(gdb) print name
$1 = 0x80483e8 "Xiuliano"
(gdb) step
5 }
(gdb) step
0x400397f7 in __libc_start_main () from /lib/i686/libc.so.6
(gdb) step
Single stepping until exit from function __libc_start_main,
which has no line number information.

Program exited normally. (No seg. fault !!!!!!!!!!!!!!)

So, where is the problem?
Thank you
Giuliano

umm. maybe you didn't look real close to this site before you posted..... notice a lot of information about paddling and boats, and very little information on writing c programs.

Try this:

- first some open boating on some nice river. enjoy nature. free your mind.

then you might consider using the data heap:

/* testptr.c */
/* gcc -o testptr -Wall -g testptr.c */
int main() {
char name [] = "Giuliano";
name[0] = 'X'; //here I get a seg. fault
return 0;
}

now that's scary - overloading the forum name
