Hello!
I discovered some strange gcc actions.
Compiling program:
---begin of main.c---
void main()
{
char *s = "Hello";
*s=0;
}
---end of main.c---
gcc -o exp1 main.c
Executing:
myhost@myhost$ ./exp1
Bus error (core dumped)
Running gdb. Stepping through program. All works fine and program
finishes succesfully. Running gdb again. Running program without
breakpoints or stepping. Line *s=0 causes segmentation fault.
OK.
Replacing char *s = "Hello" with char s[] = "Hello". All works fine.
Book "The C Programming Language" by Kernighan&Ritchie tells, that
declaration char *s and char s[] are equivalent.
Whats wrong?
Thanks.
